The only difference between wet and dry is how the extra fuel is delivered. Nitrous Oxide is composed of 33% oxygen, and atmospheric air is like 16% or something. To maintain a proper air/fuel mixture, you have to add more fuel when you add n2o.
A wet kit adds the fuel by tapping into the fuel line before the rail. Both nitrous and fuel are injected via a nozzle into your air intake, and draw into the engine.
A dry kit adds fuel by applying vaccum (pressure?) to the fuel pressure regulator. This increases pressure in the rail causing the injectors to spray more fuel.
I'd suggest a wet kit. Safer overall, IMO, and its what I run. You won't have any problems with a 50shot, except maybe eating up your clutch :) I've got an NX kit, I'll try and not be a brand whore but its complete, comes w/ thorough installation instructions, and high quality components.
Good luck

There's also 3 basic kinds of kits, I figure this will be your next question.
1.) Plate Systems - pretty outdated, poor mixing, most people avoid plate systems now a days other than for carburatored engines. In this type of system, a metal plate is sandwiched inbetween the intake manifold, or a two pieces of the air intake. Either wet or dry.
2.) Single Fogger - wet or dry, a nozzle is tapped into the intake tract, and nitrous (dry), or nitrous and fuel (wet) is injected. Descent cylinder distribution, depending on how well the intake manifold is designed. This is my setup. Good for probably close to a 100 shot.
3.) Direct Port - for big nitrous shots :) wet or dry, either way. You tap nozzles in each runner of the intake manifold. you bend hard (metal) lines. nitrous is distributed through a shower head to each runner. great nitrous distribution, the only way to really run a big shot safely.
Hope this all helps. I figured I'd type it all out, now I can just point people here for answers.
