 1). What is involved with replacing my 1.9L with a 2.1L?  Are there new fuel
 injection/exhaust mods that I must make or is it an easy swap?

I highly recommend upgrading to the 2.1L.  The difference in power is
significant.  My previous van, an 85GL with a 1.9L would struggle up a long
hill on a highway when I had it loaded up with my family.  My 90 GL just
flies right up.  I can even stay in the left lane!  Having the weight of a
Westy, you could use the power all the more. Of course, you could even
consider getting rid of the waterboxer altogether and swap in an inline 4 or
5 cyl.

I've read that the 2.1L easily replaces the 1.9L.  The fuel injection system
from the 1.9L is used.  You would need the 2.1L exhaust.
