Congrats on graduating from high school!
I've not built a motorcycle kit, but I recently read a build-up of a Tamiya Ducati in the same scale. Maybe this article can help get you started:

Oh, I'd also check out the "Tools and Tips" section of the Aircraft Resource Center web site (http://www.aircraftresourcecenter.com). I realize you're building a motorcycle, but the tipes on filling and glueing will help regardless of the type of model you build.
