Here's a good reference on the topic:
The usual way to bottle is to move the beer to a bottling bucket, prepare a sanitary priming sugar solution, and pour the solution into the bottling bucket. A bottling wand attaches to the spigot and makes bottling really easy. The beer can sit and wait until you get the bottling rig - about $20 cost.
A general rule of thumb is 1 oz (by weight) of corn sugar per gallon. A little less is good for english ales.
Here is a good carbonation calculator:
I tried the Brewers Best priming tabs one time. The package stated the amount to be added for a 12 oz beer. I think it was 3 or 4 tablets for 12 oz. It will depend on the brand most likely.
