Welcome to the world of DSLR.
Before you get confused, just go to a reputed shop buy the camera. But before that get 'e' or 'tele' quote from some of the shops and compare yourself. Check whether a memory card is included or not. If not, buy a cheapo one. buy NOTHING ELSE!!
You do not have much to check at the shop, specially when you have no idea how to use a DSLR. Only thing, trust a reputed shop like MS, Cathay.
I repeat, just buy the camera and memory card (if not included). People like you are the carrots for these shops.
Use you camera for sometime, understand camera lingo. Browse through different threads here, understand market and then identify what else you need additionally and at what price and from where. You must precisely know all these, otherwise you will be scammed!!
Your camera/lens will not be spoiled in few months if you don't use a dry cabinet or filter or cleaning tools. Understand the requirement and just buy what you need. Many of the cleaning tools, filters are just rubbish, do more harm than any good.
Dry cab is required, but you can add that after 2-3 months, don't worry!!
Buy the basic minimum and then expand based on your need.
