Marty Bergen and Mike Lawrence have written books on this sort of thing, some out of print.

Generally, with std agreements:
double = "negative double" = takeout. Use this to look for a fit in an unbid 4-cd major. You need to be stronger to do it after a preempt than after say a 1 level overcall; you want some expectation of having decent chances of making the contract when partner with his average 13 count takes it out, and of beating the contract if partner decides to leave it in. You also need some fallback plan if partner doesn't have a fit, like being able to bid NT later or support partner's opening. If doubling after partner opened a major and opp bid the other major, this shows both minors. If opp preeempted 3M, you should sometimes bid 3nt instead of doubling to find 4-4 major, if you are the one with the stopper, since partner might be stuck without one, and bypass 3nt where you are in trouble if the major fit wasn't found.

Do note that if playing "SAYC" strictly by the notes, negative doubles only go up to 2 spades, and doubling a 3x preempt is supposedly penalty. This is considered kind of ancient practice, almost all good players consider this quite inferior, and play negative doubles up to at least 3s, with many choosing 4d, 4h, or even higher. It's wise to negotiate a higher level of negative doubles if agreeing SAYC with a new partner, if you have time to do so. Otherwise be prepared for accidents. And if the only agreement is "SA", not "SAYC", playing with really old players who only played rubber bridge before, used to 4cd Majors, stayman + blkwood only, or total raw beginners, they may not know negative doubles yet and be expecting penalty doubles at even lower levels.

2nt if available = invitational to 3nt, implies no unbid 4cd major.

cue-bid = limit-raise or better for partner's suit, if partner can still get out at 3 level in his suit. Over these high major preempts like 1h-(2s) it's going to get stronger to GF or better, since 3s takes you past 3h. You still want to be able to make a single raise on less than LR values, since 3h can make and game is still possible if partner is strong, With a normal limit raise you have to just bid game and hope you make. Partner accepts most limit raises anyway, so it probably didn't make a difference. If it went 1h-(3s), then 4s is logically a slam try, 4h is just going to be LR+, and you have to give up on less than that unless partner is strong enough to reopen with a double.

non-jump raising partner to 3 level = less than limit-raise. Since you are at 3 level you don't raise with some of the weaker 6/7 counts that you would raise to 2 with.

3nt = to play, wide ranging in both range and shape because sometimes you just have no better choice, if over the preempt you have the stopper you have to bid it yourself if there's no room to probe.

new suit = 10+ pts, at least 5+ cards, forcing one round at the 2 level (if repeat at 3 level when partner hasn't shown extra, can be passed), doesn't promise a rebid. Game forcing at 3 level. If new suit is game (e.g. they bid 3s, you bid 4h), it's non-forcing. You'd prefer to have a 6+ suit for 4h over 3s preempt in case partner doesn't have much of a fit, because he will almost always pass. With 5, alternatives like doubling or 3nt can be considered, it can be a bit of a guessing game over 3S preempt. You can do stuff like double, and correct partner's 4 of a minor to 4H showing 5 hearts but also willing to play 5 of some minor if partner has no heart fit.

You'd likely find Bergen's book and Negative Doubles interesting and useful.

Googling for 'bridge negative double' should turn up some resources.

cue-bid ... GF ... LR ...

cue-bid = a bid of opponent's suit, in this context
GF = game forcing
LR = limit raise
