Compound lifts and MMa training as well will burn you out no matter what concoction you take. As for your
bulking phase you sound like a bodybuilder. Spend your time sparring, rolling and boxing, get some fights in to toughen you up too. No weight training exercise will help your boxing as much as just boxing.
If you want to train grappling, get a partner to train with , weights wont help you much as they dont mimic the strength needed to grapple, you only really get that from grappling (see supertraining), thats often why big strong mma guys often suck on the mat. When you`ve won a few fights and impressed with your skill then you could see if you can get in an MMA gym.
Play to your skills, ifyour in against a 280 pound former college wrestler then your unlikely to match him on the ground no matter how many deadlifts or bench presses you put in, instead practice your sprawls and boxing. At the stage you are probably at now weight training is`nt really required, it just takes time away from sparring and skills.
Its like a few years back Jerrel Venetian fought Hirotaka Yokoi in a pride match, Venetian was a former K-1 kickboxing grand champion, Yokoi had no stand up yet excelled on the ground. This was an MMA match and venetian and yokoi went at it yet venetian fought the fight exactly like a k-1 match, he had no sprawl or takedown defense and tried to fight Yokoi on the ground even though Yokoi was a superb shootfighter. If Venetian had worked on his defense and sprawl and worn down yokoi with kicks he may have won through better tactics. Would venetian adding 10 pounds of muscle or adding 20% to his clean and jerk max have helped him? no.
2 fighetrs i really admire are Fedor emelianko and Quinton Jackson, neither use weights in the bodybuilding sense but simply work on grappling and boxing and conditioning i.e running and circuits.
