No, we aren't doing 64-bit in the fat binaries yet, just ppc+x86.  We do plan to add that in the future, possibly later this year.

Correct, using the system one should work fine.  Note that the system one in Snow Leopard is a Cocoa-based Tk (as opposed to the Carbon one in Leopard and what is currently in ActiveTcl 8.5).  ActiveTcl will ship the Cocoa-based one when we move to 8.6.  Don't mix Snow Leopard and AT 8.5 Tk extensions - it may lead to bad results.
