Answering #3:

Hyperspace is traversed via wormholes. This has been inherent in Star Wars since the original movie came out in 1977, not something that was added later! Each ship plots its own hyperspace course. More than that, by Einsteinian physics you have a ship traversing a collapsing wormhole. It's impossible to stay still if you're being pushed by the collapse of the wormhole. Remember how it works: You calculate the trip on the navicomputer, engage the hyperdrive, then sit back and relax for some character interaction until the Speed of Plot says it's time to come out and kick the sublight drives back on. Some routes take dropping out and recalculating the next step, particularly if you're trying to evade pursuit. And if there's something that wasn't on the charts creating a mass shadow intersecting the wormhole, like a previously undetected brown dwarf or rogue planet, there's safeties in the hyperdrive to drop you out of the wormhole and into real space ahead of time.

It's not like Star Trek's subspace drive where you can wrap the ship in a bubble of subspace and move the bubble through realspace, which can sit still, relatively speaking, because it's not collapsing behind you.

Also, why would you want to sit still in the middle of a wormhole, assuming you could make the wormhole stable to not collapse in on itself with something inside it? What strategic or tactical sense would it make? You can't go outside the ship to make repairs while in hyperspace; you have to drop into realspace to do that.



I'm going to touch only briefly upon Tatooine. Suffice to say, it's a Hutt Space backwater of composed of moisture farmers, scavengers, nomadic raiders, and crime lords, with a bit of a racing circuit (because what else is there to do besides shoot womp rats?). There has to already be water there somewhere, or else you wouldn't have clouds in the sky; my guess is there's large underground reservoirs and places in the deep crevices where the water hits the surface to get boiled into the atmosphere; also likely a few hot springs in oases. But it's situated in the Outer Rim, whereas Coruscant, Corellia, and Alderaan are Core Worlds. (Naboo is the Inner Rim, situated on the border between the Core (the Deep Core, Core Worlds, and Colonies) and the Rim (Inner, Expansion, Mid, and Outer). Note that the Expansion and Mid Rims vary in width in the "south-eastern" portion of the Galaxy where Naboo and Tatooine reside, being rather slender in that region - as opposed to the wide swath along "the Slice", an older "eastern" region spreading from the Core to the Outer Rim where territory of the Colonies and the Rims are wider), which is why Naboo is closer to Tat than Coruscant.)
