LS1 question: oil pump, throttle body, injectors...not sure what I need

[almcbri]

The motor is stock right now:
98 LS1 Z28

I am ordering the 230/224/111 thunder racing cam kit next week.
I have:
Hooker ceramic coated headers
new plugs and 8mm wires
2.5" exhaust
Thats is all I plan to do with the motor for now. I eventually would like to upgrade to a FAST intake from the stock.

My question is: do I need to upgrade the stock throttle body, oil pump and injectors or is what I have going to be ok?

I have searched ls1tech, pt, and here and I am pretty much confused due to various answers.
Thanks for any help
