Shepard4 made a great point about ball vs. standing one-armed stuff: ball is great for balance but standing one-arm feels really good for functional core - standing one-arm cable press, standing one-arm shoulder press, suitcase deads and ATF squat to a one-arm press, I think he called it a thruster or somesuch.
Now how can I pass up a good shout out like that? First, K to Jim (if I'm even able to give any, that is) for telling people how smart I am.

I'm not sure I did a very good job describing thrusters last time around -- here's a video clip from crossfit.com:

Hopefully, that will do it better justice than my description. There are lots of variations on thrusters, too -- barbell, dumbbell, one handed, etc. (BTW, if you guys haven't combed through the crossfit website from top to bottom, you're missing out.) Incredible workouts that will bring your overall conditioning to a whole new level.
Now, to Guinness' original question. I've been plagued for some time now with periodic (every month or so) lower back spasms or *tweaks*. Every time it happens, I'm laid up for a week and my training takes two bigs steps back (which is not helping my quest for a 100kg snatch). For the last few months, I've been doing hyper extensions and kettlebell swings for a few high rep sets at the end of my workouts as a conditioner. The result: my back has felt 100% better, and I haven't lost a week to a back spasm in a few months now. I think my problem was a focus on the o-lifts (my primary sport) and heavy low-rep squatting without the more general conditioning necessary to maintain good "muscular fitness." My shoulders (tendinitis in both over the last few years) have felt significantly better two with the addition of period high-rep sets of pushups, handstand pushups and rows. Plus, I've actually dropped a few pounds from the conditioning, which will make it easier to make weight at 85kg!
Anyway, Guinness, before you toss away your good lifting in favor of the foo-foo bunny circuit, consider just throttling back the intensity a bit on your regular lifts and working on some basic conditioning (pushups, pullups, swings, bodyweight squats, etc.).
As for your suggested training plan, here's a few thoughts:
M- Squat 2x20 (+warmups and possibly a back-off)
Bench 5x5 (seems to be working so why mess with it?)
Row 5x5
Weighted hypers (? as far as sets/reps but prob. 2x10 or 3x8)
Heavy, dynamic ab stuff TBD
Comment: Drop the squats back down to 5x5 and just throttle back the intensity. 20-reppers will fry your back right now. Do unweighted, controlled hypers and
go for high-rep sets. Work up to sets of 15-20 or so.
W- Power clean 5x5 or 6x4 (def. gotta have some pulling in there and these are a heck of a lot easier on my low back than deads, plus i need to work on the form for them so I'll start somewhat light)
Push press 5x5 (same re. as bench)
Chins 5x5
GHR 3x10 unless they're brutal- I've never done 'em
Suitcase deads and static hold ab stuff TBD
Comment: Coming from an O-lifting background, I'm not a big fan of doing power cleans for 5's (better staying around 2-3; go for quality).
F- Basically monday but with light, higher rep stuff for abs and maybe hypers w/out weight or less weight
Comment: Okay, but how about just alternating between M and W workouts? Week 1 would be MWM; week 2 would be WMW? Something to consider.
As always, just my unsolicited $.02.
