Manasi,
The best value will be when you buy the 550D (body only) and a 100mm f2.8 L USM macro lens. Use this lens to shoot macro (insects, flowers etc), mammals and general purpose photography.
Most of the times the kit lens (18-55) etc can immediately give you a focal length range. However, in the longrun, better to buy only the best and one at a time. That will help you in saving money as well as learning the characteristics of each lens well.
Remember, the 100mm f2.8 macro lens is great and in the right hands can produce fantastic results.
