so while im deciding on which new canon to buy 400/450/500/550d there are a few lenses to choose from as well. so far my main option is the twin lens kit (stabalised) 18-55 & 55-250mm lenses. someone told me today these lenses are not that great. to me they seem like the best value and best range coverage.

I do also want to buy a 50mm f1.8 lens to allow me to take photos in low light. Im not a pro and the rest of the time i will be shooting general stuff.

will the kit lenses be sufficient enough for a general user or should i go for a 18-135mm one if its any better quality.

here are the prices and lenses of the 500d which i just might get. http://www.d-d-photographics.com.au/canon500d.htm

Sorry for sounding stupid but its all very confusing for me.
