We've always run MORT University which is training in each subgroup by students for students (along with some help from the mentors of course). We generally start in October and continue until build starts. One thing you guys could do is visit another team such as ours or anyone who is willing to help for one or a few of these training sessions to get a feel for it. Basically, if you are a young team, you may have only seniors and adults doing most of the teaching, but it depends on who you guys think knows the most and can teach others the best.
There are great learning presentations provided by many teams such as
125 and 1114. Be sure to search on here for white papers about programming and general and mechanical design. Design processes and team structure presentations are also available.
Someone on here who is not working on their history term paper (

) and has time may be able to post the links to all these or I will try to do it when I'm free. I have everything pretty much bookmarked but I'm kinda busy to do it right now.
Contact me if you need anything else. But first, search 125 and
1114's sites and also please search on here for some great resources.
EDIT:
Greg Needel has an awesome presentation about
mechanical design. We use it for our training sessions. I'm just going to be adding things on here as I have time so check back every once in a while.
