I am using XP pro 32 bit OS. Is there a limit to the amount of usable ram?

In Theory you should be able to use up to 4GB of RAM. But the reality is with some RAM being reserved by the chipsets for various things, the practical limit varies between 3 GB and 3.75 GB, depending on the MB/chipset. Same is true for Vista BTW.

64 Bit can address much more, but many MBs have a hard limit - mine is 16 GB.

Chances are that you'll have between 3GB to 3.3GB available for applications, the remainder being utilised for system calls and maybe for faster pagefile use.
