The SIZE column is useless. I forget the details why, but it often
confuses the "uniniated". The RSS is the how much heap the process
really has. The %MEM shows how much of your real memory (not swap)
the process is using.
Do you have 256MB or 512MB RAM?
(Hint: use the RSS and %MEM to compute approximately how much real
memory you have)
As for the CPU usage, what are you doing? If I open a large page in
galeon (almost full-screen window) and scroll through the whole thing
at once, line-by-line, X will peg my CPU. It's one of the effects of
doing lots of video, and using vesafb.

Looks pretty normal to me (that SIZE column looks odd, but I'd have to
research the problems with SIZE to figure out why) :
PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND
25655 root 5 -10 43080 26M 14388 S < 0.1 10.4 72:55 XFree86
(I have 256MB RAM, see how the RSS*%MEM is (approximately) the amount
of memory I have?)

I have true-type fonts enabled, I don't know how much I'm really using
them, though.

I'm not using xfs at all. For a single system, I think it only
doubles memory consumption (one copy of font for xfs, one for X).
