Thank you Joe for the comments and recommendations... I'll keep them handy. :)

Any modern processor will do.  We ship a Celeron 733 in our smallest 
model to support up to 2 T1 links and have cycles to spare.

Anything over 192MB should be fine...but it will also depend on the sise 
of your cache.

No.  That would be silly.

12GB is probably plenty for a single T1.

Don't use RAID at all for cache partitions.  It would be silly and 
counter-productive.  There are ways to minimize the damage to 
performance done by using RAIDed partitions, but it's cheaper and more 
effective just to avoid it.

You aren't going to hit any performance problems, most likely...You 
probably won't even hit the file descriptor limits of Linux (it defaults 
to 1024--which is usually plenty for 1.5Mbits, but I raise them to 8192 
on all of our boxes anyway).
I do recommend using an AUFS compile of Squid.  And ReiserFS for the 
filesystem is good too.  But even those two things probably aren't 
needed in your case.  Any modern hardware with a standard Squid install 
can probably handle it.
