Sorry for being thick Al but 30 and 15 angle?Does it just mean tighten a further bit more after torque setting ie30 degrees?

Precisely  (and harder than it sounds)

Yep, doesn't need to be exact, just work from 90 degrees as that's easy, then guess the 30 and 15 from there after the 120nm has clicked off.

Opinion does vary a little on this. Personally never had a wishbone bolt fall out on me, and find the angle tightening part a bit on the extreme side. However, having got me a couple of torque wrenches for my birthday I've been re-torquing all manner of bolts of my car, and have nipped my wishbone bolts up some, though didn't bother with the angle tightening part. Been working on Omegas for probably well over ten years now and never had a failure, but of course doing that final back-twisting angle tightening part will do no harm, the ball's in your court with that one.   

If you go down the rebuilding wishbones including Poly route (which is advised) then no need to wait until car is on the ground before torquing, just nip them up and drive away.  The order of business is...

1 Buy/acquire/beg/borrow some Omega wishbones suitable for 'conversion' - these could be cheap brand new, or old ones that'll repaint nicely.
2 Drill/press out old bushes - all of them
3 Remove ball joint (optional)
4 Grease and slide in Poly bush (no specialist tools required)
5 Press in rear genuine Vx bush ('Specialist' Garage press or home made car-jack Heath Robinson approach required)
6 Paint your wishbones
7 Fit new, quality ball joints (optional)
8 Pop on car and you're done.

Costs...
£50 / FREE = Cheap wishones - Cheap heebay ones / free old wishbones / use your existing ones if you can be without the car for a day or two
£50 = Poly bushes - Powerflex or check on here if anyones got a spare set
£20 - 40 = Ball joints (Optional) I can get some Genuine Vx for £40, half the price they are from Vx Dealer)
Satin black Hammerite or similar (comes in all over the car underside)
£36 - Genuine Vx rear bushes

So all-in comes to between £86 to £176, or between £43 to £88 per side.

Total cost for genuine Vx are £200+
Lemforders come in at something like £125+

Neither of the above will have Polys, of course, so the front bushes will need replacing at some point though age. Managed to make mine for £58 a side, that's with genuine Vx bushes, ball joints and Polys.

With regard to point 1. If there is any sign of bending or twisting anywhere on the old wishbone then these MUST NOT be reused.

The bulk of the wishbones is two metal pressings welded together. Each half should be an exact mirror image of its opposite. Any variation, however slight, means they are damaged and therefore unsafe to use
