Add 10 pounds a week for 4 weeks, then cut back to 335 pounds and repeat. If you have any gas left in the tank, try 1-2 light sets of jump squats. Start very light. Reps in the 6-10 range. If you can, do your jumps next instead of waiting til Monday.
Nothing do extreme.
Do some various two footed jumps. 50-80 touches total. Your 'right on' when you mentioned legs being fresh. It's all about legs. Because of the nature of the lift, you can train cleans and benches pretty heavy without much ill effect to your throwing.
