Unless you are working on hard maple or similar woods, you can likely get away with a little less power. Something in the 1.5 hp, or 1000 Watt power range will do most jobs, and is lighter and easier to handle as a beginner. It will do lot of bigger jobs, but it will do them a little more slowly.
Things to look for:
Plunge. If your options is one or the other, and not both, get the plunge router as it will do more
Variable rpm. I like a dial that has actual rpm values on it, but a 1-10 scale is ok too.
Power compensation. This feature has many names, but it maintains tool rpm even if the depth of cut varies. Helps prevent cutter burn and promotes and even finish. Also makes the tool easier to use, especially when starting cuts.
Depth lock. All plunge routers have this, but some locks are garbage.
Depth stops. These are height setting that allow you to set up multiple cutting depths.
Dual collet sizes. Cutters come in 1/4 and 1/2 inch shank. Handy to have a router that takes both.
A sturdy base and stable feel. The base should be wide, and when lowered into cut the router should be well balanced when you hold by the grips. It should not be top-heavy.
Lots of good brands out there. Ridgid, dewalt, milwaulkee, makita, bosch, porter cable, ryobi, and hitachi all make good tools at various price levels.
I love my Triton. I like the balance, the feel, the electonics, and the very cool plunge mechanisms. It also runs very true. <0.0005" runout with 1/2" drill rod in the collet Triton MOF001
