Motoxmall.com I've ordered from them. Good prices and prompt and free shipping, BUT some of the sponsors here are the guys that answer questions and help solve issues regularly so I would definitely consider them as well.
You will get several different opinions on tires, but I will suggest the Moto MTC. It is a good all around tire that will perform well in most applications and maintain a smooth ride. I guess it just depends on your riding style and preference. I ran 28-10-15 MTC's on my '14 800 crew with a 2" lift and they only rubbed in full lock and off camber situations. I am now running another set of 28-10-14 MTC's on my 900xp and have no rubbing, so my guess would be, if you decide to go with a 28 (MTC) they will fit and if they rub it should be minimal..
The only reason I went with new wheels on my crew was because when I lifted it, the offset on the 12" steel wheel was causing the tie rod end to rub the inside of the rim on the front (so I had to remove the lift until I could afford wheels). I had the LE wheels on my 900 but just went ahead and got tires and wheels before I lifted because of that experience. But if you are already lifted and not rubbing, you should be fine with just tires.
