Ideas for how things advance with your characters generally look good...I'll address a few things specifically as needed. Also worth mentioning, if you guys are not too happy with the character you've made, this is the time to address that. If you just want to roll something else entirely to fit into the mold, that's fine.
(Assuming, of course that this is all OK with the AMG)
I'll have a more detailed background for Sya(and the other NPCs) up in a day or so when I post their stats. Generally, the Garret/Sya thing works just fine, though he should probably understand that dealing with a fighter pilot stuck flying around a covert ops team isn't always fun. But, considering her roots as a starfighter pilot(which didn't really come up, but that's why she was down on Yavin IV...her Y-Wing was shot down), she does keep herself a bit detached from people. If anything, just means she can come off cold at times.

What was the fall out of our first mission? Did we get medals, etc? At that point I think we were all just volunteers and hadn't been integrated yet into the Rebellion. What is our permanent rank, etc? I'd figure that looking at Wraith Squadron as an example Valin would probably be a Commander, and the rest of us would probably fall around the level of Lt. with the Field officer (if Valin doesn't jon us in the field) being a Captain, or a Brevet Captain if they hadn't already proven themself.
Honestly, I try to play rank loosely if only because it can become a real headache. Besides, this is the Rebellion and its pretty loose there, too. When I DO deal with rank, however, I've taken a liking to a chart that's a compilation from many sources and done as best it can since we have no real exact rank structure for any military organization in Star Wars.

Technically, its focused on the Empire, but I just apply it across the board for ease of use. You guys are, indeed, probably around the Lt. area of things. I've already got Valin labeled as a Captain(Navy), and that's probably where he'll stay.
As for fallout...it would have mostly consisted of finding the small Rebel fleet and catching one's breath. There likely wouldn't have been any medals or celebration, if only because from that point until Echo Base is fully set up, the Rebellion is entirely on the run without much of a chance for things like that. Course, there would have been commendations, much thanks, and then the formal formation of the unit. Its mostly likely that, only a couple of days after the escape from Yavin, you guys were off again trying to find a suitable base location or dealing with something else important to the Rebellion.
