I got the siding started on my project and have made some pretty good progress so far. I've run into a couple of issues that I am not sure about, and there are still some things I don't know how to do.

The first thing I ran into was cutting the corner posts wrong. I didn't take into account that the corners wrap around both sides of the building, and the sides on the gable ends need to continue to run on up until they hit the gable soffit. I measured from the soffit on the eave walls down + anpother 3/4" or so and cut them. I then realized what I should have done was measure down from the gable soffit and add 3/4", and then notch out the part wher it runs into the eave soffit. To avoid buying four new corners, I was able to patch my mistakes, but I would have rather not had the patches. Oh and learn I guess. I pulled the corner pieces on and off a few times too, trying to figure out if I had them straight and aligned with the walls..Pain in the rear..

I did all 4 corner posts, all the soffit, and all of the j-channel that receives the siding first. The places that don't have any soffit covering them will be covered with metal, along with the fascia.

After putting my starter strip pieces on, I started running siding up the back wall and got it done pretty quick. Running the siding doesn't take any time compared to the trim work.

Here is the back wall (16' long)

And here is the left side wall (12')

corner of back and side wall -

The second problem I ran into happened when I got to the top of the back wall. the siding did not work out right and I have a nailing strip right up under the j-channel. In the picture you can see the locking tab just peaking out from under the j-channel. I can't get a nail in the nail holes, and I can't put a cut off of the next piece on to cover the lock tab because the channel is covering where I need to nail.. I don't know if it is something I did incorrectly or if it is something that could have been prevented..What happened here? More importantly, what do I do to fix it?

I did the gable end wall next and it worked out fine. there was one very small piece right up in the peak, but there was enough there where I could get a nail in it with a spacer behind it to keep it flushed out to the j-channel. It turned out great-

The last question I have is that I am not sure what I am supposed to do around my entry door and my garage door. I know I could simply run j-channel around them, but I have the feelinfg it will look cheap if I do it like that. My door is an outswing unit, so the jamb that has trim already installed is to the inside. I saw the door trim kits you can get at the store. Would this be good to put around the outside? Same thing with the garage door...I feel like it would look better with some trim boards around it, and then j-channel butting up to the back of that. How would I do the doors correctly?

We've run into the exact situation numerous times.
There are ways to deal with it.
I'll post back with a drawing and some instructions on one possible solution.
However, your siding job looks pretty good! :)
What type of caulk do you have?

You have the "J" channel against your soffit - the way that the siding ends into the "J" makes it very difficult to nail the last course of siding - having the top "nailer" exposed, doesn't look that good, either.

What you need to do, is go back to the siding supplier and get some "finish-trim"/"utility-trim"/"undersill-trim" (it's called different names).
It looks like all you'll need is 3 or 4 pieces.

You install the "utility-trim" (we'll call it "UT"), up inside the "J" - with the nail-slots in the "UT" below the bottom of the "J" (use the bottom of the "J" as a guide, to keep the "UT" straight).
If you can get the "UT" up into the "J", so that the nail-slots in the "UT" line up closely with the nail-slots in the "J" - that works too. (You might have to experiment).

Remember - center ALL your nails in the nail-slots - DO NOT nail "Dead-Tight!!!!
(On the siding and the trim!!!)

Now - what you'll do with the last course of siding is - remove the "nailer".
Take a sharp, utility knife and score as far up in the top of the nailer as you can - you may have to score it more than once.
Then bend the nailer back and forth, until it snaps off.

The problem now is - how do you secure the last piece of siding without nailing it?! (Not a good idea to "face-nail" vinyl siding - I can do it- but I wouldn't try it at home!!) :)
That's where the caulk comes in.
Cut your last pieces of siding - score off the top nailer - make sure they fit.
Then, before you put them up, put a "nice", "glob" of caulk, against the the bottom nailer of the "UT" and slide your panels up into the "utility-trim".
Put the caulk about every 2 feet - at least 2 "globs" on every piece.

If you're concerned with the siding slipping down, before the caulk sets up (depends on the caulk you're using) - take some snips, and cut some small strips of siding; wedge them between the bottom
of the last course of siding and the one below it (every few feet, leave them in for a few days).
(you may have to "stack-up" a couple layers of "strips")

I hope the caulk they gave you is "Quad" or "Solar-Seal" - or equal!
(Don't use "construction adhesive" - it doesn't expand or contract enough!)
You can use any color caulk to "glue" the siding on - it will be hidden behind the siding.

If you have a "snaplock-punch" - let me know - then, another solution! :)

On another subject -
Trim the doors out (cedar, brickmold, etc.).
Don't forget "drip-edge" over the doors and windows!!

Your siding job looks better than a lot I've seen! (Too many to think about!)

Any concerns/questions let me know!
Regards! :)
