gah lost my whole reply while going to another window to upload a pic!!!!!!
oh well, here we go again...
Personal trainer will cost money. My best guess is anywhere from $15-30 per hour. You should be able to swing an orientation for free at the gym you sign up at. They'll show you around the place for 10 minutes or so.
Best, and cheapest bet is to find a friend/acquaintance that has been working out for awhile, and have him/her show you around and demonstrate exercises for you. Otherwise, if you have a university in your area, go check out the kinesiology building and I'm sure you could find a student to help you out for cheap. Trainer is great if you have the money though - might need a few sessions to establish a routine for you, and later reducing that to once a week, eventually once a month, and one day you'll find you have learned alot of stuff to do!
Booking sessions with a trainer is just like making doctors appointments - if you miss one, you're charged anyway.
- As for the stretching, man I could go on for 4 pages about stretching! For your specific question, here is a stretch for the top of your forearm:
Man that looks absurd from that angle

never seen a picture of myself doing it! All I'm doing is holding out my arm in front of me, with palm facing down. I grab the top of my extended hand at the base of the fingers, on the knuckles, and pull my hand down and toward me.
Any other muscles you want stretches for, send me a PM. I'll snap a photo of whatever you need, just can't post em all due to bandwitch restrictions
What you have reminded me to do is to make a stretching guide thread. Maybe I'll take pics of my routine and make a web page out of it. Now if I only had free time to do that.... keep your eyes peeled in this forum.
-Cardio - personally, I do it on 3 of my rest days - so they're not really rest days

Then again I do a helluva lot of cardio. You shouldn't overdo it, especially if you're already skinny. You could start by doing 15 minutes on a bike/climber/rower/treadmill as a warmup on your workout days. Might be better that way if you're pressed for time, and plus you can
actually rest on your rest days!!!
-Not sure about websites for protein stuff... do a search and compare prices is all I can say.
-mmmmmmmm tofu.... one of my favourite foods strangely enough. Check out this thread -

Let me know if any more questions! I love to help!!
