I am building a ZFS data server using FreeNAS. I have enough hard disk space (4x2TB) for a few years, but if down the road I want to expand this out can i build another 4xHD pool? Would i need separate datasets for this second volume or can i just expand the existing ones?

You have various options. I'm assuming here that you have the 4 disks arranged as a raidz1 (like raid5) layout. Not ideal, but I won't go into discussions about the best disk layout.
