You will have to use them in full manual, if they are not Nikons, don't bother. As for the flash, it might damage the body if you try to use it (check Nikon support). Also the 7100 won't do any of the ttl flash functions, you would be better off using the built-in flash. I think you should consider the 55-300/4.5-5.6 DX VR. Its less than $400 at B&H if you buy it alone. There is a Nikon kit with a wide angle and this lens included.
I was originally going to buy the D7100 kit that has both the 18-55 and 55-300 lens. then these lenses came available and I was wondering if I might be getting a better lens and save some money. If I'm better off getting the 55-300 then I'll just do that.
