What version of FreeBSD? IIRC, in 7.0 GENERIC is SMP-enabled by default?

As for your kernel config file you should remove/comment out anything 
you don't have, e.g. wireless LAN, EISA, USB NICs, RAID, SCSI etc. - 
although be aware that USB Mass Storage devices are handled as SCSI so 
if you use any of those I'd leave everything in the SCSI Peripherals 
section and just remove the SCSI Controllers.

When you've built and installed your kernel the old one is saved in 
/boot/kernel.old so you can revert to it if needs be. It might be wise 
to rename kernel.old to kernel.GENERIC.<FBSD version> as if you build 
another kernel your first one will become kernel.old and you'll lose the 
GENERIC one. I add the FBSD version number too so when you upgrade you 
don't run the risk of booting a kernel from a previous version - which 
can sometimes cause *serious* grief if the kernel and userland don't match.
