If you haven't heard RvB is a very lax corp/alliance. A common theme is "Just do it!" and FCing is no different.
Here are some very basic things to do to get started FCing.
-Start a fleet.
-Have a safe spot. This will give your fleet a place to form up, with out getting ganked. If you don't have one some one will.
-As far as calling targets goes. Until you figure out a strategy, its best to just call the closest targets.
Other things to remember.
The opposing FC wants a good fight as much as you do. So get into the RvB community chat and find out who the other FC is. Most FC's are more than happy to accommodate for new FC's.
Most people don't try to FC because they don't want to be responsible for loosing every ones stuff.
Just remember they all undocked knowing that they WOULD (not might) lose that ship.
