(x-post for Fitit) Can someone point me to a good writup on the types of bard and plates out there and the description and use of the varios benches and stands?

So Fitit helped me sort out my calorie problem today (thanks guys and gals!) and now I have another more awesome problem. Now I need help adding to my home gym.

I have a well to do mother-in-law (First world problem) who is a shop-a-holic and she always gives me a pile of junk I do not want for both my birthday and christmas.

So I was talking to my wife and she gave me an idea. She will talk to the mother in law and convince her to buy me one thing, weights.

I have never lifted olympic weights before and need to learn about the different types of bars and plates and so forth so i can create a list, my wife will feed one item off this list to my mother in law per holiday and instead of a pile of useless junk I will get one useful and awesome gift.

Where can I get a good understanding of the different sort of bars and plate, benches, and other devices so I can know what to ask for? What Items should I ask for and in what order?

What does the hivemind think of the stuff sold by Rogue Fitness?

Many thanks for all your advice! If it matters I have half of a 2-car garage to put equipment in. I have a copy of Starting Strength on the way. Help me make use of it! Many thanks!
