Create Transport route / layer (should be done by BASIS guys).
Create Package with afore created transport route and transport request will be proposed.
Create Function group and 'BAPI' or better said, create function module. Assign development to transport.
release transport SE01 / SE09
Import transport STMS.
In a nutshell. But to me it looks like you don't have that much experience, so better try and start somewhere at the bottom, by creating simple reports, create transport request etc....
