In reply to Avinash Aujayeb:
Yes it will work fine. That's a "semi-compact" chainset and a popular ratio. If you live somewhere hilly you'll find the climbs a tiny bit tougher in your 36 but not much. If you live somewhere flat you probably won't even notice.
Can't you buy just the chainrings? Where is "over here"? Surely you can get some locally?
If you are changing the chainset, are you also changing the chain and cassette? It's probably a good idea.
