I have limited experience with repitching, BUT I just finished listening to an episode of Brew Strong with Jamil Z and John P. If you don't know who they are, Google them. They know what they're talking about. Anyway, they said that if you're going to repitch, don't just pour a new bag of yeast in. Instead, make another starter and wait until it's at high krausen and then dump it in.
One other thing to think about is that with most beers you can expect to drop about 75% of your OG to your FG. That said, you can expect to drop about 82.5 points leaving your FG at about 1.0275. You're really close to that so it might be done.
Not to throw something else at you, but I'm getting ready to brew an RIS that has an estimated OG of 1.123 and an FG of 1.020. That's a bigger drop than 75% which is what you're getting.

Also, they have a four-part series on brewing High Gravity Beers you could check out before your next brew. One other piece of info is the section in How To Brew. Maybe see if it helps.
