+1 on adding your LR before the sand. Lost a couple of critters cause of that.

Second, going all LR inst necessary, to save some $ you can add mostly base rock and a couple chunks of LR to seed the rest, after a couple of months you wont see the difference.

Now for the sand, you could get some "dead" sand and seed it with just a cup or to of live sand, your LFS will sell you some for cheap i'm sure. My LFS gave me about 2 lbs worth.

I dont really like the bacteria in a bottle kind of deal, I use a big cocktail shrimp put that in a micron bag and just dump it in the tank. The shrimp will start to decay and decompose which will create all the bacteria you need to get your cycle started.

Oh and do add everything at once, like nemo said it will just extend the cycle time every time you add something new to the tank.

You can run all your lights during the cycle. that way you know how much heat they will give out like Dyngoe said and make adjustments accordingly.
