Hi Bharat,
I know what all must be going on in your mind.As relocating to altogether a different country isn't that easy.Well i am not an expert but would like to ans few of your questions.It depends totally on a person how long he takes to adapt to a different environment.It cant be generalized.About the attire in the office it depends a lot which organization you are working with.Though you are free to wear whatever you are comfortable with.Formal Attires are always appreciated it depends a lot on your own comfort.Whether you more comfortable wearing an Indian outfit or western.So you needn't worry on that front as Delhi is very liberalized on that ground.I would also like to recommend you to go through the blog-realtydigest.blogspot.com for more details. Incase i can be of more help to you without reluctance let me know.
