Euribor or Bund is good place to start.
Introductory Guide: BE CAREFUL it's a big boys market
The sb spreads I have seen have been horrendous D4F currently quote 97.83/86 in Sep Euribor whereas on exchange it is 97.83.5/84 at Eur12.50/tick (0.005) that is a very wide spread if you wanna lift..
FI is a professional market if you want to trade it actively the only way is direct exchange access. Other than that I think you are OK if you are playing for developing trends. They certainly do trend now and again but you may want to wait for an indication that the next tightening cycle is on cards first.
I would start out by trading the schatz and hedging you position with one or may two option against it. It doesn't move very much in comparison to the bubl and the bund making the options cheap. You will also have more time to learn about the markets before you go broke!(or a least it will keep you in the game until you learn how to make money)
