Which Live Rock?

Which Live Rock?
Hello all, I am either going to start a 55 gallon SW tank, or move my 120g
FW to the 55g and make the 120g a SW tank. I do not plan on having Corals
and Inverts at this time, but do like to colorfulness of Corals. My
questions are below is you all can help:

Which live rock should I get? Is the Fuji Live Sand good? They all look
great at http://www.liveaquaria.com/product/...d=24&pCatId=393

1) Is Fiji Live Sand (Crushed scleractinia) good?

2) Which live rock? Will this work with regular lighting (fish only lights)?
Are they truly colorful rocks?

Tonga Branch Live Rock (Scleractinia)

Kaelini Live Rock (Scleractinia)

Tonga Deepwater Live Rock (Scleractinia)

Tonga Ridge Live Rock (Scleractinia pcs.)

Fiji Premium Live Rock (Scleractinia)

3) Should I get a cleaning crew from the start? Or wait for algae to bloom?

4) Should I spend the bucks on a UV Sterilizer?

Thanks for now.... I will have many more questions before I make the
move...
