I have over 150 items in my TF2 inventory, but all I can sell are my crates, keys, and Genuine Items. How do I know what is eligible for selling, and what is not?
Is it actually possible to sell any item from my TF2 inventory? (Do I have to, say, sign up for another Steam Service before I can freely sell all my items?)

Currently, you do need a premium account to sell items. The wiki also says that "In order to sell an item on the Steam Community Market, the user must buy one item on Steam per year, and then wait 30 days after purchase to begin buying or selling."
It's also limited to tradable Genuine items, Vintage items, Festive (both Unique and Strange) weapons, Botkiller weapons, Strange weapons, Unusual hats, crates, and most if not all tools.
You can see what items of your inventory can be sold by using the "Show marketable borders only" option of the backpack viewer. This also shows how much is the item selling for.
