How can I check the amount of free RAM (not STORAGE memory) on my N800? The "free memory" statistic at the top of "top" doesn't ever seem to change. Any ideas?

You can install htop from maemo repository http://maemo.org/development/tools/
htop is slightly better but still the fundamental problem here is that you really don't want to monitor "free memory" in linux. Free memory is wasted memory, the best for the system is to keep free memory at zero. For finding who eats the memory watch "RES" (resident set) column in htop and substract "SHR" (shared set).
You can also run something like this (maemo-developers, Subject: Re: C - Hildon - Memory usage Date: Tue, 12 Feb 2008 16:50:40 +0200 From: Eero Tamminen )
to see private memory taken by specific program.

Code:
awk '/Private_Dirty/{sum+=$2}END{print sum "kB"}' /proc/$(pidof myprogram)/smaps

If you just want an overview you can run 'free' in the terminal it will look like this
Code:
-:~# free
total used free shared buffers
Mem: 62176 60328 1848 0 8
Swap: 255992 20 255972
Total: 318168 60348 257820

@ericdkirk,
How did you create a 256MB swap on your 770? I assume 770 since you only seem to have 64 Meg builtin RAM.
