Set me up on a program

OP - sounds like Rippetoe would be great for you. Not sure, but it sounds like from your description you have a bit of "skinny fat" going on, your height/weight is actually fine, but you don't have enough muscle. Seems like you've never done serious lifting, so you should probably go ahead and buy the Rippetoe book and start with really light weights. Saying you have "weak knees" probably just means you need to train them, which is what this program should do.
