Vista Home Premium SP1

Pentium Dual Core 2.0gHz

400gByte Hard drive

3Gig RAM

Question:
According to the store I bought it from, I have a 32bit version of
Vista which will read up to 3.5gibabytes of RAM if I install two 2Gig
sticks. In order to read all 4Gig(or 3.9), they told me I'd have to
install a 64bit version of Vista.

Is this information correct?

The machine is more than fast enough for my needs now, even with
chubby Norton AV 2007 running in the background, etc, but should I
throw in a second 2Gig stick just to get the few extra horsepower from
the 0.4Gig it would read?
