I'll try to answer your questions here. Congratulations and enjoy the flight.

Yes, correct.

Although I'm not sure what you mean exactly, yes 30 minutes is a reasonable and perhaps slightly conservative estimate for total time (disembarking from first flight + transit security + walk to lounge + walk from lounge to departure gate for 2nd flight).
Are you going to try and go to both Wing and Pier? If you only go to one, actually it won't be the end of the world even if one flight is gate 4 (...farther than gate 1) and the other is gate 71.
Just remember, there are transit security facilities scattered throughout the single-terminal airport: "transit" is another way of saying "go downstairs/arrival to upstairs/departure".
You will likely know your departure gate for your 2nd flight when you land, either when you're in the air or upon arrival if the gate isn't displayed on-board CX873 as they often are prior to landing. If you don't mind which lounge you use, when you deplane, I'd recommend using either the Pier or Wing F most "on the way" to your next gate. But really, 2 hours is plenty of time to go to both, even if the gates aren't perfectly located.

Not that I know.

Not a problem to get the opposite sex, I do it all the time. Just ask on board when they give you your kit. Not a big deal.

Also not a problem to wear your t-shirt. Dress code in F is no different than J class, PEY or Y in my opinion. Although if you're implying it's okay to waltz around in your underwear...that I have to assume you're kidding...right? Just as that wouldn't be appropriate anywhere else on the plane, it is not appropriate in F class either...

you are going to have a lot of time in the lounge then....which, although isn't my cup of tea, sounds like what you're going for

Ha, have you read FT and seen what some people do on the blogs? People shoveling bottles of water into their bags, stealing bottles of Champagne, trying to spend overnight, taking an entire buffet tray worth of sushi, and god knows how many other things. Spending hours in the lounge is not a crime. You're overthinking it a little too much

. Enjoy yourself.

You may go between the lounges as many times as you like...no restrictions.
"The Cabanas" in Wing F have the only baths, if you're asking about bath tubs.
I prefer The Pier for showers. If you care, Pier has brand-name amenities while the Wing doesn't. Actually, both Pier J and Pier F have brand-name amenities. Wing doesn't.
Since you have so much time, you may as well go to all the lounges. Pier J is particularly nice IMO and if I had 12 hours I'd probably be there instead of the F lounge.

Not really. Although flights to the USA often depart from gates 3-4, and to a lesser-extent 17-18. However sometimes they are also at random gates in the 20s, 40s, 60s, etc. If you have to bet, bet on gates 3-4. Those are the most common departure gates for late night CX872 and CX880 (SFO and LAX midnight departures).
I'll add the final caveat that I certainly wouldn't be spending 12 (or 6...or 4) hours in the lounge if I could avoid it. But I understand the excitement and am not going to try and dissuade you. Enjoy.
