The MBP is fine, but you need more power and screen real estate - i.e. the Mac Pro and a good monitor. But the problem is that now's not the greatest time to buy a desktop. Its very likely that the line will be updated in the next six weeks or so.

didn't the mac pro just get a processor update (clovertown)?

1st thing to upgrade... more RAM.
 
personally I'd spend more on the processors (8-core) as it's something that can't be upgraded and get less RAM and a smaller monitor for now and upgrade as you go.

another option is to wait for a refresh but the way things have been going lately with apple, these are coming more slowly.
Huh? You can ABSOLUTELY upgrade the CPU's. Go with the base model and upgrade as see fit. Not to mention you can sell off the old CPU's when upgrading.
