There wasn't an option to upgrade to 64 bit processing. It doesn't hurt asking, but I suspect that the price would be prohibitive with buying something this inexpensive.

The RAM will be 2x1Gb, so that should leave two DIMM slots for more RAM. I've learned to pay attention to how the RAM is divided up versus the available slots for RAM.
