If your doing it on the cheap then you won't have a smooth ride, most cheap coilovers (JOM, hot tuning etc.) are all made in the same place and just re branded. The ride is pretty poor, especially when your really low.
Wheels is a very personal thing, lots of wheels will fit without much hassle. Anything that is 4x100, not bigger than 16" and with an offset between et25-et40 should fit straight on depending on width.
