I bet this isn't entirely true, or at least, it's not quite what you meant. You may not have a certain physique or bodyweight goal in mind, but would you mind gaining 10-15 pounds of muscle and bodyfat if it meant increased performance?
That's fine, and legit in your current situation. But as a heads up, around here, that phrase is like walking into an old school dojo and saying "I'm interested in kicking ass on the streets." Not always well-received.
13 pounds in a single month is big progress. Are you sure most of that was muscle?
Asking for "the best strength program" is like asking for "the best food." There's really no single answer.
I'd say swap to a better-designed program for now. It hasn't been terrible, but like caveman said, your deadlift is stalled because you're overtrained on it. There's a reason Rippetoe only suggests one working set of it. And you're going to failure in a high rep range on the bodyweight exercises, which isn't really beneficial for much at all.
Enamait knows his stuff, absolutely. But have you looked in the Combat forum here (especially the "'How to Train' Questions" sticky at the top)? A lot of guys seem to like Wendler's 5/3/1 plan or DeFranco's Westside for Skinny Bastards template.
All things considered, this would not be the worst idea in the world.
