Scott,
I agree with your "don't think too deep" philosophy, and in fact wish I
had adopted it on my previous lab attempts.
However, in this case, Tim stated the requirements will not allow him to
disable IP routing on the Cat3550.

What about "default-gateway"???
At that point, you'll need to disable ip routing, but does that fall
within
the confines of what you are or are not allowed to do?
Things don't always have a big convoluted fancy solution! Particularly
if
the notation in your lab for 3550 reachability is someplace in the early
LAN/Catalyst section... Labs are fairly logically written in that
regard
(for the most part).
So while NAT/PAT, or some other interesting solution may work (you still
need to get to the router before NAT takes place), think of the simple
things.
Just my opinion...

Sorry, no cigar. That, along with additional static routes, default
routes,
default networks are not allowed.
