Steals isnt really required while learning SSS.
You certainly cannot raise with any two cards to steal from BU / CO / SB as SSS as if someone attacks you you have to go all in. You cant call, see a flop, catch something random and continue because you have zero implieds. If you want to expand to stealing you raise with more PPs and more aces, some suited kings, not any two random crap. Stuff that can be in front or has good equity in an all-in situation is what we need, not stuff that is playable postflop. Ironically the push-or-fold charts from the SnG/tournament section are somewhat useful for selecting hands to steal with playing SSS.
W$WSF is won $ when saw flop. Basically it should be in the high 40s at the very least. We only get into a pot with premium hands as SSS so we should be winning a whole lot of them.
I suggest expanding your continuation bet policy, as 34% AFq is only about 1% higher than your chance to hit a given flop with a hand such as AK. You can conti bet vs more than one opponent as we are representing a very, very tight hand range, despite what the cbet article says.
If someone min-bets at you (1BB) and you hold AK on a flop like
Q :spade:7 :spade:3 
Consider raising or just shoving. Their bet is often representing a flush draw or some rubbish pair, and by shoving you wont give them odds to call. Even better some flushers will call because they are bad at poker and suited hands are too pretty to fold, and unless theyve also got a pair you are still taking the pot half of the time with air.
Now, the silver cbet article also waffles on about "1/2 pot to 2/3rds pot" bet sizes. Scrap that. Its rubbish. You cbet what you would bet if you had the hand you are lying and saying you have! EG, we hold AKs of diamonds on the flop above. We are going to lie and say we have AQ, KK or AA (doesnt matter which really). We would need to protect from the flush draw.
As I posted above its common to have 16 BB left and a 9.5 BB pot. We are going to bet at least 8 BB to protect our hand properly from a flush here, which means half our stack is going in. If half our stack is going in, so is the other half, per standard SSS bet rules. Dont mess around with readable half-pot cbets on drawing flops. Shove it as if you mean it.
You will lose a stack now and then, and suck out with your overcards now and then, but there is an aweful lot more fold equity when you do what you would do if you actually had the cards rather than some wanky half-pot bet that you only make when you are lying. Anyone who cares to notice will start raising your cbets with air and turn you into a virtual ATM.
If in any doubt, simply say to yourself "what hand would I be representing by betting here?". Then ask yourself "what would I bet with that hand in this situation?". Then go ahead and bet it.
