Most of the rules on that Wiki are usable for the core system at the very least as reference, but yeah, some may require a bit too much ciphering for to be useful for new players, sorry about that. I was running a Survivor style game with everyone on an island and a Christopher Walken type celebrity as the host, and it had just gotten to a combat portion, and the last of my six starting players abandoned the game, spontaneously, about the third week in, in the play by post - I was even doing a twice a week update. I'd run it twice before but it was on personal forums of people I knew online but that weren't specifically for RPGs (Obiwan's UFO Free Paranormal page in fact) and I had a dozen players and they ALL played through the game all the way to the end... so you can just never tell.
I'm hoping that fairly soon, myself and another member will be able to release a very nice and helpful special free supplement for GMs and Players, that will provide some useful "corralling" of information into one place, but I really would rather not say any more about it currently, but I'm very proud to be able to work on it.
Regarding things like the Abomination and the skill max, keep in mind that while this or that particular skill is limited as noted, the attribute itself, and all its sub-attributes ARE still raised, when you raise them at character creation, for later use, once that max limit has disappeared, so while, yeah, it's a pain to put up with to start, it doesn't totally negate the raises later.
And of course, this goes without saying, but it IS your game, you're more than welcome to simply ignore the maxes if you so desire and make whatever ruling you want. It's what I did when I first started running the game, to help the players get interested and not roll their eyes at the fiddly bits, so you might consider that, and later on you can decide if you need to enforce the max AV rule later, if you don't use it initially. I also occasionally went the hybrid path, where I allowed players to exceed it but limited some other feature or skill or even attribute for the first session, or even removed a skill entirely. There are a lot of options and there's no real right or wrong answer, and although it can be confusing, in a way, I think I kinda benefitted from just jumping in, seat-of-the-pants style and saying "Hell yah sure, take that 18 Guns skill with your Ninja!" and later on when he was mowing down people, I thought, "Hmmm... mistake noted, will not be repeated."
