Tyler,
Before you get any corals, you will have to upgrade your lighting. 17watts of 50/50 isn't much light for a 29 gallon coral tank. The amount and type of light depends a lot on the type of coral you want to keep. However as a very rough rule, you want about 4 watts per gallon (3 watts per gallon at the minimum). So for your 29 gallon, you will want about 120 watts.
To give you an idea, I have a 12gallon nano tank with 24watts. That's 2 watts per gallon. I have a very difficult time trying to keep any coral in that tank. You're at roughly 0.6 watts per gallon.
As far as corals good for beginners, look for soft corals (zoas, leathers, toadstool, mushrooms, ricordea, and so on). LPS are also relatively easy to keep. SPS can be much more difficult. When you upgrade your light, let me know and I will try to hook you up with some corals (leather and mushroom).
