A few weeks ago I think I summed up the Nats strategy at the trade deadline as simply "Don't screw things up". Based on those low expectations the Nats passed with flying colors. They didn't trade anything of import to 2012 and beyond, and they used the opportunity to bring in some decent talent. True, they didn't get any "real" prospects, but they weren't offering up any "real" talent in return. The only failing was not getting a CF but that isn't something that has to be done now. All in all I think it was a successful, if uninspiring trade deadline.
Now because it's fun to put arbitrary, completely meaningless grades to theses things - let's grade the trades
Gomes deal - Days later the deal still is a head-scratcher. Gomes makes the Nats a better team at the plate vs left-handed pitchers. That's not worth giving up anything decent and the Nats gave up a couple of minor leaguers that were decent. Not more than decent but decent. It's not a terrible deal but only because it doesn't really matter. It's like going with Bud Light over Miller Light. C-
Marquis deal - this is exactly the "good" deal a Nats fan would reasonably expect when trading Marquis. The Nats get a young A-ball prospect with usable skills that could develop into something special, (although it's unlikely). Zach Walters isn't super young (he'll be 22 in a month) but he does seem to be developing both the power and patience you'd like a player to develop at his age. The thing likely to hold him back is a high strikeout rate (that's ok in the majors but when you K a lot in the minors it can mean you won't hit anything in the majors). Next year will be huge for Zach. B+
Hairston deal - this is exactly the type of great deal a Nats fans wouldn't think they could get when trading Hairston. For a 35 year old super sub you hope for whatever you don't expect a guy that has a good chance at making the majors but that seems to be what Erik Komatsu is. Granted he doesn't appear to making it as a good player - his so-so defense and lack of power likely make him a 4th OF - but that's still more than I thought Hairston could get and that's admitting that I misread Hairston this season.

We could try to rate the non-deals but without knowing exactly what was on the table it's pointless. I will say that I would have done Storen and Bernadina for Span in a heartbeat. Storen and Lombardozzi would have taken a few more pumps of blood, but I would have also done that. Why? because here's what Span has done in the majors compared to Lombardozzi
Span : .289 BA, .361 OBP with plus fielding in center
Lombardozzi : . . .
Also the Nats would have control of Span through 2014. That's good enough for me and if Rizzo balked at these dealsm (or losing someone for the sake of a Desmond or Clippard) he's making classic mistakes of overestimating the worth of relievers and your own guys. But again - we don't know and like I said before these deals can go down in the offseason... or next year's deadline.
All in all I think you have to be happy with the way the deadline went down. A couple more deals (why is Nix still here?) would have been nice but the Nats are a better organization today then they were two weeks ago. That's the ultimate goal.
