I can answer a few of your questions:
1. I don't think so. I'm not sure there are any "semi-official" mods for BG1.
2. I didn't have any problems. I downloaded and installed all the programs in the order I was instructed and everything was okay.
3. I think so. I think that everything has to be done before the final battle, hence the name. I never tried though.
4. None of your gear follows you into SoA, unfortunately.
5. Not sure.
As far as the game goes, DSotSC is a nice little add-on, especially if you've played BG1 a million times and need something else to do. The only thing is though, by the time you finish, you are pretty powerful. It almost makes the game too easy. There are new items that turn your tanks into wrecking machines. My AC is -9 on two of my NPCs, and I did all this before I went to Cloakwood. It almost made the game not fun (almost). For instance...

When I did the werewolf island in TotSC, I did the entire thing without needing to rest or reload. I took very little damage, and only needed a handful of potions and healing spells. There were a few levels of the werewolves' ship where I took no damage at all. I'm kind of dreading the final battle, where I know I'll take down Sarevok on the first try. Powergaming, hack and slash type of play is not my thing. I guess you could argue that you don't have to use the equipment that DSotSC provides, but in the interest of roleplaying you have to ask yourself if your PC or NPCs would really not use an all-powerful weapon because it makes things "too easy". Anyway, I'm babbling. Give DSotSC a try, the storyline is good and the new NPCs are kind of cool. Plus you'll get a kick out of one of the accents that an essential NPC has. High comedy...
