What do I do if I don't want to lose any more weight(cause I don't need to) and just wanna get big and ripped?

Increasing your weights and decreasing reps will help you bulk up. Aim for the 8-10 reps instead of 12-16. Also, keep a high protein diet and it'll help you increase your muscle mass.

Big and ripped? I guess it depends on what you mean by "big". I hear that and see "bulk" in the title of this thread and I think bodybuilder-type physique. If that's what you're going for then P90X won't get you there. I would concentrate on more traditional weight-lighting. Heavy weights, low reps. Culrs, presses, squats galore. Yoga, wall squats and all the "max-reps" stuff in P90X are not mass builing excercises.
Look to the informercial for best-case P90X results. If that's what you want great, listen to Corp_T.
But if you want bigger and bulkier you should try something other than P90X.

google jurassic mass. it seemed to have worked pretty well for my friend.
