What to do about the WR position?

I'm 2-0, but probably the weakest of the three undefeated teams in my 12-team league. I'm solid in most places, but my receiving corps worries me, and the Bengals' woes and Galloway's recent ankle injury are making me even more nervous. My team:

QB-Kurt Warner, Philip Rivers (start 1)

RB- Willie Parker, Brandon Jacobs, Chris Johnson, Jonathan Stewart (start 2)

WR- Reggie Wayne, TJ Houshmandzadeh, David Patten, Joey Galloway (start 3)

TE- John Carlson, Owen Daniels (start 1)

K- Josh Scobee DEF- Giants/Eagles

The way I see it, I have three options to pursue over the next couple of weeks, or until the bye weeks come and free up more spots for me:

1. Stand pat, hope Housh and the Bungles come around, wait for Galloway to heal, and go with Patten as my third WR for a spell.

2. Dump Galloway now for a FA, best of whom are probably Justin Gage, Sidney Rice, or Chansi Stuckey. Not much.

3. Try to trade Chris Johnson (or maybe Jacobs), since I'm pretty deep at RB, for a top-25 wideout. There's one guy in my league, for example, who has Welker, Hines Ward, and Eddie Royal starting at WR, with three more on his bench. (CJ for Royal, is this a good deal?)

What do you think? Which of the three choices would you make? Thanks!
