Here's what we're looking at:
2010 (if uncapped):
ERFA: Guyton, Lockett
RFA: Connolly, Gostkowski, Mankins, Ninkovich, Taylor, Woods
UFA: Bodden, Burgess, Faulk, Green, Hanson, Neal, Seau, Watson, Wilfork
2010 (if capped):
ERFA: Guyton, Lockett
RFA: Connolly, Ninkovich, Taylor
UFA: Bodden, Burgess, Faulk, Gostkowski, Green, Hanson, Mankins, Neal, Seau, Watson, Wilfork, Woods
The first scenario seems to be the more likely one.
In that case, Guyton and Lockett are re-signed to ERFA deals.
Gostkowski and Mankins are tagged with the 1st and 3rd tender (~$3M). That could be risky, because you don't know if there's a team out there that values Mankins enough (like Curtis Martin) to give up the 1st and 3rd picks. And if that team is, say, Pittsburgh (which needs OG help), then that 1st round pick is going to be fairly low. This could be a motivating factor in extending either or both of these players.
Taylor, Ninkovich, and Connolly are non-tendered (see Britt - not going to pay $1M to Ninkovich for lowest tender). That leaves Woods - easy decision, 2nd rd. tender @ $1.6M (wouldn't want to do the original pick compensation b/c he was a UDFA).
UFA-wise, you let Burgess and Seau walk - TBC's extension probably sealed Burgess' fate. Faulk is still a very valuable player in this offense and should get a new deal. Neal and Green are also guys you'll want to keep around, with no ready replacement at either position (Brace and Ohrnberger will be competing for reserve roles still). You let Hanson, Bodden, and Watson play out the season and see where things stand then.
Then there's that massive question mark: Wilfork.
