Lamp Post GFI protection

I'm installing a lamp post in my front yard soon. Here are a few details of the circuit:

-Power comes from a switch inside of the front door.
-Wire (14-2 nm-b) runs into the basement and along the floor joists.
-15A circuit
-Goes into 3/4" conduit and down the basement wall, into a junction box, out into an 3/4" LB, then out into the yard.
-Everything after the junction box will be 12-2 uf in 3/4" conduit (I had 12g laying around so i'm using it.)
-18" burial depth

1.) If i would like to GFI protect this circuit, does it make sense to use a GFI recepticle in the junction box?
2.) Will this be a problem if the outlet is only powered when the lamp post is on?
3.) I had initially not planned on the recepticle, so the junction box is about 36" off of the floor. Since the recepticle is used for light protection only, will this be a problem that it is this high off of the ground?

I do have a few others, but i may get these answered inadvertently. FYI this will be inspected.

1) This will be fine, although unnecessary.

2) Shouldn't be.

3) No

you can get a dead front gfci as well if you don't want to put in the receptacle.

I'm here to learn too, i do mostly commercial/industrial/new construction and this place is a great way to pick up tips on residential from some good electrical minds. Excuse the spelling, my phone has a mind of it's own.
