If you're a complete 'newbie' I would suggest starting with the 18-55mm IS kit lens because it's very cheap when bought with the body and it's not a bad lens at all. Make sure it's the IS version though. Other options would be the 17-85mm or 15-85mm but they are a lot more expensive (but better quality). Try the kit lens and if you get more into it, you can always upgrade and not lose too much money on the kit lens.
What sort of photography are you intending on doing?
If you are planning on photographing sports I would go straight for the 55-250mm rather than the kit lens which you will find too short.
Portraits I would go for the 50mm f1.8.
Landscapes and general photography/finding your style and preferred subjects, the kit lens will be fine.
IMHO that would be the best course.I guess I will probably do a mixture of portrait shots and landscapes. to some extent it will be a case of playing around to find what I enjoy taking photos of.
The "Canon EF 50 mm f/1.8 II Lens" is only £89.95 at Amazon, so I think i'll go with the kit lens and then buy this one in time.
I soon added the Canon 50mm f1.8 and Canon 55-250mm IS f4-f5.6 to complement the kit lens. Good image quality for the money in my view!

Thanks for all the replies. In case anyone is interested, I bought the Canon 550d with stock lens kit from Dixons using the following deal.
http://www.hotukdeals.com/deals/can...dixons-30-canon-cashback/929069/#post11161058
£519 minus £30 canon cashback minus £26ish Quidco cashback = £463 for a brand new UK 550d!
Damn, the 550d is out of stock now (unless you go for the 18-135 lens), and the code no longer applies as I tried the d3100 as an alternative. That'll teach me to be so slow!!
Hope you enjoy yours anyway.
Edit: Just sussed out it applies only to orders over 500.
Blimey that didn't last long. It has now been reduced to £539 at Amazon though, and you get the £30 cashback on top of that as well, so £509 in total.
Well, I'm afraid you're about 8 posts [and however many days] shy of being able to hit the classifieds herebut whichever you choose, remember two things..
firstly, don't beat yourself up about not having the top-o-the range... a gifted eye can produce Pullitzer images from a Box Brownie...
and don't think for a second that this is going to be cheap! Honestly, cocaine would be a cheaper habit... and so it starts....
