You'll get plenty of great advice here
A good place to start would be to go back and read some of the older threads on the forum. You might be looking for topics such as:
Brass Frame versus Steel frame
Molding your own bullets/roundballs versus buying them
Powder loads
The camparison of Colt style versus Remington style revolvers
Bore lube
Cleaning
Just look down through the titles of the threads until you come to something that looks interesting.
For those who are just getting started with the first pistol, Cabelas has a "Pistol on a card" set up that has (pretty much) everything you need for a couple days light shooting (Fam Fire). That normally goes for about 250.00.
Cabelas has a sale on right now so that price might be lower. Don't cut yourself getting it open.
At a minimum you need:
Pistol, (Never ever ever call it a gun. It is not a gun)
caps,
balls,
powder,
powder measure,
bore lube (for the first couple days, you can get away with Crisco, but you will grow out of that quickly. Its easy to make your own and it doesn't put too much of a strain on your marriage.)
gun oil (most of the guys never let petroleum based products touch their shootin irons.)
Someplace to shoot and something to shoot at. ( I recommend a Ford truck...Never shoot at a Chevy truck
)
There are plenty of additional things that willl come in handy. Most of that will be things you choose on your own and should not be overinfluenced by others.
Most of all, when you have a question...any question, come to this forum. You will have four good answers (plus one long, rambling, pointless, verbose, misinformed, opinionated diatribe from me) within about 24 hours.
