For reviews, I recommend
Modelling Madness. They have a good set of reviews.
For inspiration, I recommend two sites:
HyperScale and
Aircraft Resource Center. The models on HyperScale are awe inspiring, while on ARC they are a bit more like what the "human" modellers build. I wouldn't expect to build models like those on HyperScale right away, but with practice and learning some techniques here and there, you will be able to down the road.
I have used
Great Models and
Squadron to order models and extra stuff like decals and detail sets. If you can, I would go into a local hobby shop. That is where I go when I get paints and some kits as well.
As far as recommending kits, I would start with a Revel/Monogram kit or even Tamiya. The Revelogram kits may not be the "best" or most accurate, but they are inexpensive and you can see if you really want to get into the hobby. The Tamiya kits are engineered very well. Their F4U series is probably the best one in 1/48th. As you get more comfortable, I would move on to Hasegawa and some of the more "exotic" Tamiya kits. They are more expensive, but very good quality kits. The latest Tamiya kits are very good and go together very well.
Enjoy the hobby, and remember, you only have to impress yourself.
