The carbo block is worthless, if you decide to dose with Flourish, you have to dose the full line of their products, and on a 125 that can get expensive. As far as lighting goes your best bets for a tank that size are T5 lighting or MH.
A pair of these would do the trick http://www.thatpetplace.com/pet/prod/204838/product.web and would put you around 2.5 wpg
Pressurized CO2 is the way to go, you can get a reliable setup for around $300, and have it fully automated with a solenoid and PH controller (CO2 will lower your PH)
Lighting and CO2 will depend alot on your plant choice.

It would be worth it to put a 3-4" bed of Flouite or Eco-complete under your gravel, 10lbs won't do a thing for you, you'll need at least 100.
