wa/wb in position, is to call if the other guy bets and (generally-depends on opponent and baord) to bet if he checks to you. The idea is to maximize your profit when ahead and minimize your losses when behind. Here is an applicable scenario. You raise on button with A5, BB 3 bets, flop comes A29r. You are either way in front of BB's pp or way behind his bigger ace. If you raise you just stop him from bluffin a weaker hand and you pay more to a stronger hand, so calling is just better.

wa/wb out of position is check/call the flop, check/call the turn, and bet the river (again opponent and board specifc). Imagine button raises and you call in BB w A5. Flop is A29r. You want him to bet his weaker hand while minimizing the amount you pay to a stonger hand. The river bet is designed to prevent him from checking behind with his pp. The river bet is particularly effective when a backdoor draw comes in on the river because he will be unlikely to raise you even if you are beat, but will not likely fold his weaker hand. Also, you can typically fold the river is he raises you (dangerous if you have zero read on your opponent).

Stop and go is when you are out of position and your opponent raises you on the flop (applies on the turn too I suppose, but it usually referenced wrt flopp and turn). Rather than 3 betting him and leading the turn, you decide to call his flop raise and lead out on the turn. Most common time to stop and go is when you think someone is raisng for a free card on you (flop has two suited cards for example). Here is an example where i think it is appropriate (others may disagree). MP player limps and you raise in SB w QQ, BB folds and MP calls. Flop comes Kc Th 5h. You bet and the MP player raises. He could easily have a flush draw, JQ, or have paired the Ten or 5. You don't want to give him free cards, but you also don't want to spew chips at his pair of Kings. You just call the flop raise (stop) and then lead the turn when a card like 3s comes (go). If he raises you again you can more confidently fold (again, dangerous without a read), or call the turn bet and fold on the river.

Free show down is a play that you use when you are in postion and you have a strong enough hand to go to show down. Also, you suspect your opponent either has a slightly better hand or a worse hand that has draws. The idea is that you are going to pay two bets to a better hand any way so you might as well make sure that your opponent pays two bets with his weaker hand. An added bonus is if your opponent is weak and may fold a better hand or a hand with a lot of outs.

Here is an example. You are on the button with KJ and you raise. SB and BB call. Flop comes J98r. SB checks, BB bets out, you raise, SB folds and BB 3 bets, you call. Ace comes on the turn, and the BB leads out. The pot has gotten relatively big so you want to get to show down. If you raise and he 3 bets you can confidently fold knowing that he either has a str8 or set and you are drawing dead. Most opponents would just call with there 2 pair once the ace hits the turn. The idea of raising the turn is that it doen't cost you anymore when you are behind (because most hands that marginally beat you will check the river), but it maximixes the price for your opponent to see the river when he is behind but drawing. For example, in the above scenario, the BB might have QJ, JT, or 9T. A good player might even lead the turn and then Check/Fold the river unimproved with one of these hands.

Not sure what rope-a-dope is. I think that is when you check raise a guy on every street. Sort of the opposite of stop and go.
