To answer (probably) the biggest question, "can you do it yourself?" Yes. Yes you can but it's a lot involved process with many, many steps that require planning.

Considering you're thinking about getting a ready made shortblock, theres really two main things (that I can think of off the top of my head) that you will have to pay close attention to. 1) the most crutial part of the job would be following proper procedure for torquing down the heads. 2) Setting the timing belt in the correct spots. The timing belt is more or less as "simple" as connecting the dots, but can easily be screwed up. If you're replacing the timing belt, it's imperative you actually read any and all paper work that comes with the kit. Often timing belt kits will come with cautionary information about installation procedures and anecdotes that should not be immediately set aside.

Once you have the heads on and the timing belt on, it's just a matter of slowly working your way through all the parts.

Go to the liquor store and grab yourself a crap ton of boxes. Like 10 or 15 of them. As you remove parts, categorize them (example, AC compressor and all of its bolts and brackets is box 1, alternator and bolts etc is box 2, and so) and place them in order you took them off. When you're ready to reassemble, you put the parts on in reverse order. Take pictures. Lots of pictures. Transfer said pictures to a laptop (so they don't get lost with your screenshots of funny memes on your phone) where you can organize them into folders corresponding to your parts boxes. If you get stuck at a spot and suddenly figure out how it comes apart, take a picture or video to help remind you how it goes back together.

briansmobile1 on YouTube has a video on proper head torque procedure.

There's various other videos about timing belt installation.

This isn't exactly rocket science but if this isn't something you've done before, take your time. I'd recommend wrapping your head around the idea that this may likely NOT be a one weekend deal.
