Cleaning up Arranging harddrive

I have an imac dedicated to logic. What is the best way to arrange my hard drive so I can have my songs, loops, samples, midi files etc. all available and organized so i can "easily" get to them from within Logic?

Anxious to hear your ideas.

I won't comment on organization other than to say I'd consider getting (at least) another drive to record to/from and possibly stream samples.
