Single folder: Yes. Use /sdcard/andboot/. This is how the all-in-one package is set up.

Backup Apps: Yes. from the terminal, go to /data/app/ and copy out the .apk file for whatever app you want to save. These saved apps can be reloaded from the AndroidApps folder, or by using Astro to navigate to them and open them in the app manager.

Photos: I'm not sure. Try moving the Gallery apk from AndroidApps/Media to AndroidApps/. I'm not sure this will help. Photo handling might be just busted in this version. You could try the system.sqsh from TheBrilliantMistake's package at xda-developers and see if that works.

Startup.txt: There's a lot of fragmentation in these. Many of them have deprecated pieces that just haven't gotten cleared out. The one I have posted in the all-in-one package has pretty much everything necessary for general use (including dummy entries for rel_path and overclocking). I mentioned rootdelay a few posts ago, but I've never had to use that, and neither have most people, so I'm not sure how much attention it needs. There are a number of options to increase debugging info, but, again, those are not necessary for general use. Searching this thread for 'cmdline' might get you more that I can't remember right now.
