Would I compile an SMP kernel to make use of Hyperthreading?
I've got a Dell Precision 360 that has a P4 with Hyperthreading. My question (as above...) is will my 2.4.9 kernel that works as it is make use of the features enabled in the processor, or will I need to recompile/upgrade to 2.6.x to make these features work?

I'm running the SMP kernel when using Fedora.
If you want to build you own kernel be sure to include it...
You don't need to upgrade as far as I know of, most distro's supply both normal as SMP kernels.

It definitely won't work with a 2.4.9 kernel. I think that hyperthreading was added in 2.4.17, but I'm honestly not sure about that. I do know for sure that it's supported in all 2.6 versions, though, so if you want to be sure as well, upgrade to 2.6.
And yes, you will need to compile the kernel with SMP support. The hyperthreading cores will each appear as a separate CPU if you start top or check /proc/cpuinfo, etc.
