In order the full 4 GiB of RAM is recognized from a 32-bits OS (having
PAE enabled or not), your motherboard has to provide that functionaly
because there's still a small amount of RAM that is used for devices and
it has to be remapped from the BIOS.

I would go for 64-bits but only when installing a new system completely
from scratch.

I would rather use Synaptic to view "in live" what's going on :-)
Kernels are usually installed in paralel so right after you trigger a new
"linux-image" package there will be a new entry added in GRUB's menu to
boot the latest installed kernel and of course, the others.
