'Who' -
Looking at your set-up, I'd think about a Mon.-Wed.-Fri. weekly plan where you would perform high demand CNS exercises (this is where your plyos would fit in) with some lighter general conditioning on Tues.-Thurs. I would stick with 1-2 days of plyo work (sounds like wed. is already a heavier plyo day for you so that's fine) with one of those days being more moderate. Perform your plyos before your lifting on these days.
Lifts I would perform without hesitation are: Back Squats (full), Power Cleans, Snatches, Hang Cleans. The latter 3 are olympic lifts(OL) or variations of. They are critical for power development in jumpers. Do these types of lifts on your heavy days (M-W), again performing plyos prior to them. Upper body exercises on these days should consist of some type of pressing movement (flat bench, incline, mil. overhead, push press) as well. Everything else could be considered 'auxiliary' or 'complimentary'. You can choose a couple other exercises to perform here.
If you go with this plan of lifting heavy on M-W-F, reserve T-TR for general strength circuit type work. On the messageboard you can find many different ideas for circuit training…check it out. If you don't do it already, I would begin working with med balls 1-2 days a week as this training is excellent for core strength and general fitness. Med balls can be a great compliment to the circuit training on these days. Look up med balls on the messageboard as well and you will find some great stuff.
Putting it together for you this would look like:
MON.- Plyos
Squat, Clean, Press lifts
TUES.-Med Balls
Circuit Training lifts
WED.-Plyos (heavier if you wish)
Squat, Clean, Press lifts
THUR.-Med Balls
Circuit Training lifts
FRI. - This day could be a recovery day for you if you'd like to
perform another high CNS day (similar to M-W) on Saturday.
When involved with the OL's, make sure you have a coach who is knowledgable/certified to teach you these lifts, as they are highly technical and can be dangerous if not performed correctly. The back squats are irreplaceable and should be a part of any jumpers workout, 2 days a week in my opinion (sometimes 3 depending on the training period).
Also, if you don't already, get a good training partner you can work hard with….this can be invaluable as you might know. If you need anything else just drop a line…but like I said before, browse the messageboard and you'll also find some fantastic stuff regarding training! Take care and I hope this will help you get started.
