Ok here is what I've been given.
This 3 tier cake seems simple enough although I'm not really sure what tip to use??? My step brother also wants a gumpaste topper of him holding him pregnant wife's belly. I have done some figures, but never of people. Where do I even start?
I have just recently started figure modelling. I really love it. I bought all of aine2's tutorials. They were a great help. Forgot what her website is. but you can google lorraine Mckay, and go from there. I also buy clay modelling books, just subsitute fondant or gumpaste for the clay. good luck
Looks like all round tips, of various sizes.
Sorry, I've never done figure modeling 
Paula1234 is right, aine2 walks you through modeling step by step. She has a tutorial on a woman, if you want to buy just that one and not the bears, etc. right now. I don't remember the exact price, but it wasn't that bad, as I recall. Also, you can print out the tutorial and have it available for yourself forever! And yeah, clay modeling books are usually really well laid out with step-by-step.
Post a pic!
extraicingonthecake.com is Aine's blog site. It's awesome. There are all sorts of little extras on there and lots of tutorials!!
