Welcome (not only to this forum) but to SASS!!!
I'm a newbie shooter as well (just started last month along with my 13 y/o daughter). While each club is different, I would encourage you to go to the shoots at your local club and ask lots and lots of questions. Most members, in my experience, will let you shoot a variety of pistols, rifles and shotguns in order to help you make up your mind what works for you.
In my situation, I thought that purchasing pistols first was the way to go. It is far easier to borrow (and yes, my fellow club members literally line up to allow me and my daughter to borrow their stuff) a rifle and/or shotgun. So far, we've purchased 3 pistols. My daughter and I share one pistol, but I'm looking for a match for her (Thunderer). I will then probably purchase a shotgun and then a rifle which her and I will share until we each have our own set.
I do reload, so I show up with the appropriate ammo (what most of us would consider powderpuff rounds at 750-800 fps), but one member even gave us ammo to shoot on our first shoot (I didn't have any appropriate ammo). I'm sure there's a butt in the crowd somewhere, but so far, I've not met one. After a month of "getting into it," I've met some of the warmest, hospitable folks you could ever meet who care more about the growing of their sport more than who's gonna shoot top dog or whatever.
Oh yeah....I'm looking at the Rossi 92's as well. I don't think you can get a lever action any cheaper. My plan is to buy one of those first and then our "second" rifle can be a 73 or another typical variety if we so choose. If you get the 92 first, then you could probably trade and/or sell it to upgrade to the 73 you really want -- assuming that remains what you really want when the time comes.
Good Luck!
