Yes, I can see the benefit of using what you are familiar with. I started
out deploying on Windows servers, but I found many times struggling to get
Windows to work easily. Stuff as simple as the differences in how paths
are done can screw you up.

Again, just a recommendation to use Linux, certainly not a requirement. I
would argue that it will be much easier over the long haul, even if you
have to learn some Linux basics.

As far as 32 bit vs 64 bit, I would never deploy anything on 32 bit
anymore. Any hardware less than 4 or 5 years old should be 64 bit capable.
Windows 32 bit Java has that 1.5 gig (roughly) limit. As you noted, 32 bit
can handle quite a bit of usage. Again, depending on the OP's
circumstances, a few different choices now (while initially deploying),
might make life easier later.
