Good to see the efforts here already helping people
You pose some good questions which have been omitted:

Depending on your FF program there may be benefits to booking the appropriate code share on a flight as the same fare basis earns different miles whether on one airline or another (eg disc Y on BA gets 25% QF miles, but the same disc Y on the QF codeshare earns 100% QF miles). This mostly applies to disc Y fares.
The only other instance that i know of is for QF FF members who only get status bonuses on QF/AA/BA (eg CX metal and CX flight number - no status bonus miles, BUT CX metal BA/AA/QF flight number - full status bonus miles).

Firstly some airports (eg LHR) do not charge transitting pax the airport/departure tax - hence if layover is up to 24 hours, you don't incur this tax.
Secondly, you can "stop" in a city even though you are out of stopovers (eg in continent of origin only 2 allowed) but this will not count as a "stopove" if less than 24 hours.

Although it'll be obvious that you're traveling on discounted First or Business fares, how often will you be singled out? Can the ground staff see you're on a RTW and pick on you because of that, or will you be put in the same pool as other A/D passengers? I've flown on D fares a few times and I've never had a problem.
You are treated as all other A/D pax - most agents dont even know its a RTW ticket. I have never had a problem in D.
