Build Order Advice

[LSUMurse]

So, I am trying to put together a timeline, of sorts, for my build. I know some things should be done before others, or at least it is easier if done in a particular order. So I was looking for advice on what order makes for an easier build. With the amount of experience on this site, I am hoping to learn by yall's mistakes.

Background:
1968 1/2 ton 2WD Stepside LWB. 307 with a Powerglide. Stock rear (so, I'm guessing 3:73). Manual steering/brakes. No A/C.

Intent for truck:
The wife and I are looking to either put a slide-in camper on her or tow a small 16' trailer behind her and travel around the states. So, fuel economy is a little bit of a concern.

What I want to do:
Convert to power steering
Convert to power brakes
Convert to front (possibly rear also) disc brakes
Replace Powerglide tranny with a 700R4
Body patches (both rear cab corners, rear cab support ends on both sides, RH rocker panel, both kick panels, and I would guess I will find more as I go along)
Put in A/C
Put in a wood floor (currently has a sheet of 3/4 PT plywood)
Replace 2 bbl carb with a 4 bbl carb and intake manifold
Paint

I'm guessing there are some things that can be done at any time along the build and others that really should be done in order. For instance, I am guessing the carb and manifold should be changed before the tranny due to the linkage geometry.

Any advice would be greatly appreciated. If there's something here that I missed, please let me know. Thank you all in advance.

BTW, Board, meet Rosie.
