Need parts suggestions on new-used SVX

[Huskymaniac]

I just bought a 1996 SVX with 72K miles on it. The owner is an elderly man who was supposedly meticulous with his cars. However, I want to make sure I do whatever I can to avoid issues.

1. What automatic transmission fluid should I use? I have seen people suggest Amsoil, Royal Purple, Mobil 1 and Redline. I have heard that synthetic can help the transmission run cooler and extend its life. The car has 72K miles so would it make more sense to go with Redline or Royal Purple since they are high in esters and would condition the seals? I have looked closely at their specifications and Redline D4 is incredibly good at holding viscosity at both high and low temperatures and has a nice high flash point.
2. Should I add a friction modifier to the transmission fluid? I have had luck with it extending the life of a binding center differential in my 97 Outback. I added it to the standard Subaru ATF. The most commonly suggested one is the Lubegard in the black bottle. They claim it also aids in the transfer of heat. Any comments on whether or not this is a good idea? Redline suggested against it since they thought it might make the seals swell too much if used in conjunction with their D4 ATF.
3. Do I need an external filter since I have a post-93 SVX? If so, what brand/model of transmission filter should I use? From what I understand, the newer trannys already have two filters. One is under the battery and I can't recall where I heard the other one is. Do either of these need to be replaced when I do a filter change?
4. Does the 1996 SVX need the transmission cooler and, if so, which is the best model to install and where should it be installed? I heard that it should be before the stock cooler so the fluid won't be too cool prior to re-entering the tranny.
5. Do you guys have a preference for wheel bearings, when and if they need to be replaced, and the synthetic grease to pack them with? I found one online, NTN, that looked particularly beefy and had a warranty. There was also Timken and Beck-Arnley.
6. I plan to replace the rotors, when they need to be replaced, with high end rotors. It looks like Centric sells their cryo-treated rotors for this car. I just bought a pair for the fronts on my Tribeca, which I am replacing because they warped. If they work out well there, I may try them on the SVX. There are also rotors from that Beck-Arnley company and cross-drilled rotors from Powerstop. Those were pricey but are supposed to be particularly good at staying cool and not warping. Are their specific pads to use to deal with the heat/warping issue? I put Akebono ceramics on my Tribeca because they were supposedly gentle on the rotors.
7. I am looking at wheels and there seems to be some discrepancy on wheel offset and bolt pattern. I have seen offsets of 52 and 55 quoted as stock and I have seen 5X112 and 5X114.3 quoted as stock. Which of those is correct and what is the main source of interference to be concerned with? It appears as though the concern is the outside edge of the tire rubbing against the wheel well.
8. I have also been told that the front differential can have issues too. What gear oil do you guys like?
9. What is this MAF I saw in a few posts? It appears to be another potential point of failure.
