This doesn't really answer your question but you can get a cool scoring program from http://www.musicease.com/ (shareware/evaluation) that is really easy to use. Kinda like a word processor for music. Then you can save as a midi file and import into cakewalk etc.
Multiple staffs etc. are really easy and you can print good hardcopy too.
