depending upon the offset of your wheels, 35s are not a guaranteed fit. i have 33s on mine with a 2'' level up front (rear is stock). i have +20 offset wheels and mud flaps on front. with the mudflaps installed, i dont think 35s will fit.
and it was already mentioned that 33s with a 3'' may look small. id have to agree with that. i have a 2'' and i think my 33s look small.
with a 3'', i HIGHLY recommend getting longer shocks for the front too. if you dont, your stock shocks will fail prematurely. after seeing how easy it was to do when i installed my springs, i suggest to do it right away. if you dont, and you have to change the shocks 10k miles down the road, you have to tear everything apart that you did to install the lift. so its 100x easier to do right away when everything is already apart.
i got all my stuff from thuren suspension. doug, the owner of thuren, told me the newer 4 generation dodges do not need sway bar modifications with my setup. maybe with a 3'', but he told me not to waste my money when doing the 2''.
also, as others have said, you will need an adjustable track bar. if you do not get one and reuse the OEM bar, your front axle will not be centered under the truck anymore.
