Skills should be self-explanatory. If you're not sure what category to use just pick the one you like. A couple fiddly points - any kind of action stunt like jumping between cars or climbing a tower should probably come under Fight, and I'm thinking of having some low-level mysterious psychic powers to give the Heal person more to do.
Talk - do stuff with people
Drive - do stuff with vehicles
Fight - do stuff with weapons
Heal - do stuff with organic systems
Fix - do stuff with inorganic systems
Everything is d6s. You get six d6s to distribute among these skills, and that's what you roll when you're using the skill. You're allowed to have no points in things. So Mal from Firefly might be like
and then if he wants to attack Jayne he rolls 3d6. Pick a target number from 2 (super easy) to 6 (super hard). Jayne's guard is up so let's say that's 5 (hard). To win, Mal has to roll 5 or above at least once. If he rolls 4 5 6, that's two successes, so he wins twice. If he rolls 1 2 3 he fails and Jayne gets to shoot him.
The simplest way to manage hit points is that each player starts off with three Wounds and whenever someone rolls a success against you, you lose one. So if Mal rolls 4 5 6 he hits Jayne twice and Jayne has one Wound left. If he loses that he starts to bleed out and Simon has to roll Heal to stabilize him. There's no initiative - the person who says they attack first is the person that gets to attack first.
You can also use your turn to Help people. Say how you're helping them and then give them your dice from whatever skill you're using. The only restriction is you can't give them more dice than they already have in that skill. So Kaylee can help Mal fly the ship by dicking about with the engine to make it run smoother, but even though she has like 5d6 in Fix she can't give him more than one because Mal is not that good at flying ships. Mal would then get to roll 2d6 and still probably be shot by Reavers.
Your players start with a spaceship. Talk is captaining and comms. Drive is piloting. Fight is manning the guns. Heal is life-support and shipboard ecology. Fix is engine room. Each player also gets to pick a category on the Stuff table, below, and roll on it. They can't pick something they have no dice in.
