Until today I've never tried to use a disk drive with my Atari 400. I've always used cassettes. I have two 1050 drives that I use with my Atari 800XL and I thought I'd try them with the 400.

I booted the 400 with DOS 2.5 and a BASIC Rev. C cartridge. It started to load DOS and I saw that it said it was loading the 130XE extensions (this seems weird) and then screen turned to garbage.

I'm guessing this is RAM related as my 400 only has 16K, but I've never read anywhere that this wasn't enough for DOS. Is this enough RAM to load DOS 2.5? Is there a compatibility issue with DOS 2.5 and the 400?

Most 400 Ataris don't have enough memory to use a disk drive. I think this is your problem.
