Also look into investing in one or two books. Maya At A Glance sprinsg to mind and would resolve all your "lack of knowlegde" issues, it covers the entire UI in detail. Also look into Maya 7, or 8 Foundation book. Both are available in Amazon, Autodesk stores and online in general. So check your local bookstore and online for the cheapest price. I would go Amazon as you can get them 2nd hand at a fraction of the price.
