Entry level DSLR with kitzoom and telezoom, then.
You're in luck. Currently for some odd reason Nikon has published two entry level DSLRs which are INFERIOR to their predecessors. So I would advise you to get the D5500.
Combine that with the 18-55 plus 55-200 and you should be golden.
Alternatively if you're OK with buying used, you might consider a used but well treated D7100 with low enough shutter count. That will give you better autofocus, weathersealing, second card slot and many more features lacking in entry level bodies.
For landscape you might want to get a tripod and a polarizer filter. The tripod is for being able to shoot longtime exposures in low light conditions and for having braketing to handle especially harsh lighting situations (as they are common with landscapes) and the polarizer helps with reducing reflected light, a very essential tool in landscape photography.
In the long run you might want to get a Tamron 10-24 f3.5-4.5 VC "II" wide zoom as well; its currently clearly out of your budget. You can do panorama series until then, though.
For wildlife having only 200mm as the upper limit is not much, depending upon the animal you want to shoot, so again you might want another lens for that area; however it should be pointed out that it get really pricey really fast in that area.
