Gant, if he checks back in here, would be able to answer better than I could on how to blend a solid lifting plan in with any sort of combat sport. I actually improved, and gained a lot of punching power, when I stopped lifting. now I lift again, and the power is coming back, but I'm still a bit tight. I also now workout on my own and tend to nurse hand bruises every week or so. Of course, YMMV.
Regarding doing a madcow intermediate plan with all of the other stuff: I would think some sort of auto regulated, RPE set up like Mike Touscherer (SP?) has set up in RTS would make more sense. I've only glimpsed what he does, but it seems that people do pretty good with something like this. Eduardo Chile's training log includes RTS PL stuff along with BJJ. You should check that out too.
Also, you would be surprised at how poorly Tabatas and 'metcons' will prepare you. Fighters run. They do road work, and they rarely do metabolic circuits. In order to go long, you need to go long.
How many days per week are you now training on the mats?
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
