I'm going through a similar action myself right now -- I'm trying to kill as few humans as possible. (I made an exception for Benny, and raiders who attack on sight.)
Skills: I know you said you don't want to do locks and computers, but you'll have to for some things, so keep lockpicking and science high. Prioritize speech -- you can get out of a lot of fights, and even better, get XP for it. Maybe go for survival and/or repair, and go after the challenges for crafting.
So some early-game missions to help you out? Skip Primm entirely, head straight to Mojave Outpost. You'll get Ghost's quest there, which just requires you to go to Nipton. In Nipton, you'll get "Cold, Cold Heart," which just requires you to go to Mojave. Easy, non-violent 250 XP. Not much, but it'll get you started.
From there, make a beeline to New Vegas, by way of Novac. In Novac, do Boone's side quest, because it's quick and easy and non-violent. In Freeside, take the peaceful route through G.I. Blues, hook up the Followers and the Garretts, and do the Wang Dang Atomic Tango. Once in New Vegas, go talk to Mr. House and deal with Ring-a-Ding-Ding. After that, you should be able to take down Talent Pool pretty quickly and peacefully.
By the time you get through all this, with perhaps a little bit of minor side adventurism, and you should be at least level 10 or 12.
You can totally do this. I Mr. Sandman'd everyone, and killed off most of everyone in disguise so I barely lost any reputation. After I dealt with them all, I exited the bunker (without blowing it up and still completing the 'Destroy The Brotherhood' mission by killing everyone, or at least all major characters) and Veronica was none the wiser. All was good.

For 2 of the 3 weapon-confiscating casinos, yes.
I tested it out using the
killconsole command on the three door greeters at The Tops, The Ultra-Luxe, and Gamorrah. After being killed, no other greeter took their place.For both The Tops and The Ultra-Luxe, killing the doorman had no effect; meaning once they're dead you're free to enter the casino and gamble, etc.
With Gamorrah on the other hand, if the doorman dies the Omertas will immediately become hostile towards you, thus barring you from using the casino.
I also tested the difficulty of killing the greeters without using the console, and it's surprisingly a lot easier than I expected. Using a Stealth Boy and a hold out weapon, you can simply sneak up behind them and kill them without anyone else noticing. This can also be done at a relatively low level, thanks to the effectiveness of the stealth boy.
