Picked up an Apple II plus, green screen monitor, and Disk II on Craigslist.

I am new to the Apple II world -- can someone identify the two cards and third "add on" I found inside the machine?  (See pictures attached).

I also have a question -- when I tried to load a couple of games, it said that it could not run them because the diskette required 64k of RAM.  I was confused by this because this Apple II plus has the language card in it and therefore HAS 64k of RAM.  Also one of the games (Oregon Trail) is one that I see all sorts of Apple II plus-es running on Youtube..

Also, sometimes when I turn on the power to the machine, the disk II's red light turns on and it sounds like it is working (whether there is a disk in there or not) and it never does anything....

Thanks!
