Are we to understand that you bought a motor before researching the work and parts that are necessary for doing this swap?
I ought to say "search, this has been covered a thousand times" but I somehow feel that wouldn't quite be fitting.
There's a lot more that you need aside from belts and filters. Please do search, and not just on this site. An SR was my first swap, too, and there's so much information readily available that I never had to ask for any help until it was up and running, but running poorly (turned out to be a minor wiring mishap).
This may be a good purchase, if at least to help you understand what you're getting into:
