Ice, I'm primarily a poker player, but I take baskets seriously enough to pretty much move to Vegas for Dec thru March. Because I handicap, I do NOT put that much effort into line watching. I just make the effort to get the best line available when I bet. Nonetheless, finding a weak number sometimes makes a lean into a bet for me.
I often wish downtown had some poker action, or at least, high enough poker to interest me. It's very easy to hit books there. I often start my day at the cheapo diner at the Wild Wild West, jump quickly from there to the Palms/Gold Coast/Rio, go down Decatur to AZ Charlies (Stratosphere) if they're hanging any weak numbers, and then a quick jump to downtown, all told making for a 10-book check in about 90 minutes, without ever going on the strip. After that, I'm off to play cards on the Strip, and looking for lean-breakers at the Venetian/Harrahs/Mirage/Wynn. Those 4 entail some tedious walking, but I really, really don't mind the exercise.
You've probably figured out already to otherwise stay off the strip. Even walking from one out to another there is time consuming if you have to cross the strip on foot.
My general game plan is to have my list of plays and leans, and then bet my plays at the best price available, and bet leans if I find a good price (a soft number gets me off the fence). I mostly bet offshore, but I make so many bets that I always seem to tap them out, so I need the ease of some cash betting outs, too, which Vegas provides.
I think experience will quickly teach you how to most efficiently get around town, and to which books you should go.
90% of the time, if you have at least 5-6 offshore outs, you'll find at least a tie for the best number there. But Vegas is often a few minutes behind the offshore moves, so if a number is going quickly against you, jump in live. Just keep a low profile, because they hate no one like they hate the guy who keeps betting just ahead of the blink.
As far as dealing with a crew, I'd lean against it. There are lots of gamblers I like. There are few I trust. All it takes is one dispute like "Ice, you got down on me at +6? I said +6.5, so no, I'm not taking the ticket from you," leaving you to eat the loss. Or you ask someone up the strip to get down for you at a good number hanging there, and they don't get back to you until 30' into the game, and if you're trailing badly, they got down, but if you're winning easy early, "hey, sorry dude, I got shut out." Tons of little penny ante angles to shoot, so petty you'd think no one would stoop so low. They'll stoop. In Vegas, they'll stoop.
Oh, btw, start learning poker. First, super small stakes online, where it won't cost you nothing to learn the fundamentals. then 1-2 live. Anyone bright and not-emotionalistic (you sound like you have both characteristics) can be making, within a year, $20/hr playing the 1-2 NL games on weekends with tourists. That's not an exciting income, and I'm making a conservative estimate (without bragging at all, I'd make a fair bit more than $20 in those games) but it does mean you'll never go broke. And it'll give you something positive to do in the casinos while waiting for scores to come in or lines to blink. And poker's fun for it's own sake. So, just start, slowly, to fit it into your repertoire of gambler's income. Play 100k hands of .05/.10 blind NL on the internet, and then play live. Those games are stunningly soft.
