I say get the camera and a lens or two and start shooting. Don't spend any more money until you know what you need and don't rush into buying stuff until your are more than sure you need it.

FWIW it portraits are what you think you would like to shoot don't bother with that really long telephoto even though the price is attractive. Get the 50mm 1.8, I believe you will really like the way you can get the backgrounds out of focus with that lens and the size makes it really easy to carry and shoot with.
