Newbie question here:
I’ve looked up what Cash In and Buy Out mean and would like to know if the following train of thought is accurate or really doesn’t matter:
When doing a heavy workload WOD (heavy Deadlifts + Squats + something else) is it wiser to “balance” it out by Buying Out with an aerobic or gymnastic type exercise?
When doing the opposite, an aerobic or gymnastic type exercise, “balance” it with a heavy pumping routine, like a ton of pull ups/push ups/air squats/etc.?
Regarding the Cash In, I know the “Official” CF Warm up and to substitute certain exercises depending on the WOD, but are the other less “Official” Warm Ups depending on the type of WOD?
I’m new to CrossFit (did my first exercise yesterday) so please excuse my ignorance. I’ve tried to get up to date on it but there is way too much information to digest in one go, or two, or a dozen 
Thx in advance!!!

I’m afraid GD is the only one who can really advise how he structures the Cash Outs at BX. In general Cash Outs are gymnastics based skill work no matter what the WOD. But that is a very general rule and you could find a host of exceptions with 5 minutes searching.
As far as warm-ups go, whatever rocks your boat a does the job. Honestly
Here’s a few rants, I mean some helpful information on the subject.

What does Crossfit say about warmups?
this: http://www.crossfit.com/cf-info/faq.html#General7
(And like your dad, I’m gonna remind you that the main site: http://www.crossfit.com is a WEALTH of information.
But if you’re too lazy to click a link . . . here it is:
The “official” CrossFit Warm-up is in the April 2003 CrossFit Journal.
3 rounds of 10-15 reps of
Samson Stretch (do the Samson Stretch once each round for 15-30 seconds)
Overhead Squat with broomstick
Sit-up
Back-extension
Pull-up
Dip
Note that for a workout that’s dip or pullup-centric, you might want to do something else in the warmup.
Note, that’s a lot of work. That is 30-45 pullups. In a way, you might say that this isn’t just a warmup, it’s a Big Dog warmup. Unless you’re super fit, this may be too much for you, even at a moderate pace.
So also see this:

Also note the context of the “official” warmup: It was a recommendation by Coach Glassman, with regard to designing a crossfit warmup. That said, variety is the spice of life and one of the foundations of Crossfit. As you progress you’ll learn to warm up in a variety of ways.

Coach Glassman’s original article where he described what has become the official CrossFit warm-up is now available as a free download from the CrossFit journal site.
You can get it from the horse’ mouth here.

Oh and in case your reading hadn’t turned it up, buy-ins aren’t warm-ups, they’re post warm-up skill work.
