How to replace a section of drywall? (Total Newbie)
How to replace a section of drywall? (Total Newbie)

Here is the section which I cut out after it was damaged by water:

What are the steps to repair that after I remove the baseboard and cut a piece of drywall the same size as the hole?

Then to I glue it in? nail it in?

Then spread is it joint compound over the crack? Sand and paint?

Nasty patch for your first fix------You will need--a small roll of paper tape--the patch--

A good 6" steel blade and maybe an 8" or 10" blade. A sanding sponge.

Pull the small section of base board- screw the drywall to the studs--add a bit of scrap blocking to the right side if the stud is to narrow.

I suggest a bag of easy sand 20 (20 minute set)--Mix a small batch--pack any voids--add a line of mud on both sides of the corner--cut a piece of paper to length--fold embed it into the mud with your 6" knife press gently you want to leave enough mud to hold the the same for the top seam.

Clean your tools--get a cold drink--check your work in 20 or 30 minutes---

Using the 6" blade--knife off any globs,boogers and high spots----Then add another thin coat using the 6"blade---clean tools -wait--knife off boogers--add another thin coat with the wider blade--

That's about it--sand if it looks O.k.--add more coats if not. If the job were larger I would have suggested a different mud.---Mike---

When pulling off the base boards I found some more spots of wet/weak dry wall, so I cut that out, and not have about 10 times that area to do, 8 spots total.

What would be the best mud for that? Is the premixed stuff any good?

The premix is fine--much easier to sand--

If you have a bunch to do--switch to 45 or 90 minute bag mix to fill voids and embed the paper--

Then the bag mix for the first coat --switch to the blue top bucket mix for the final top coats--

much easier to sand-however it take 12 to 24 hours to dry--use a fan----that is why I suggested the fast setting stuff when you had only one small patch.--Mike--

Yep, setting compound saves time. And if you use mesh tape on any repairs it is a must for at least the first coat. OP will need paper tape as oh'mike stated as it's an inside corner and the method is dead on....
