So... today's attempts: Spent a while trying to get the ball joint out "properly", using tips from Triumph dude mentioned above. Didn't work. Cheated and took it out by using the bolts. Can't get the one attached to what I think is the track rod end off at all.
So. Before work started:

One hour later:

So I gave in and tried cooking instead....
Also bought some shock and unlock freeze style stuff, as I can't convince dad not to buy WD40 - even after reading him these things and a Triumph guy from the club explaining why it wasn't much good on stuck bolts

If it's the ball joint on the track rod end (ie the one from the steering rack), the "bolt" will be tapered and won't just pull out. There are two "easy" methods, but beware, both may damage the rubber boot.
1/ Put large hammer on one side of the housing on the arm and get a second hammer, knock seven bells out of the joint! This shocks the pin out of the hole. It sounds crude, but it usually works for me (with practice, you can avoid damaging the rubber!)
2/ Get a good ball joint seperator. The small ones with a bolt sticking out of the bottom of a "tube" are OK. Again, the secret is to tighten the bolt up to the thread on the ball joint and then hit the bolt with a hammer - sharp wacks rather than gentle taps! Don't tighten the seperator's bolt as far as you can - some "DIY expert" borrowed one from me and did that - I was left with some scrap metal and a bent bolt!
With either method, make sure you leave the nut on the ball joint - with some gap between nut and housing - otherwise the track rod will fly around in a spectacular manner (dangerous in confined spaces!). It also saves the thread from damage if using the seperator.
You will probably find a "Power Bar" a better alternative to a ratchet for really tight bolts - a nice 500mm long swivel bar (the Halford's one is good!) will move a lot of tight bolts - I have many on the tractors that need it!

So; Trunnion Dissembling:
First I thought it was far more difficult than I expected. Then I realised I was simply hammering the concrete floor away from underneath

So moving onto a plank of wood I dissembled it; cleaned it out and it's now drying ready to be rebuilt. Any ideas on what grease I should use?

Aa

NEVER use grease in these trunnions, they
must be lubricated by straight,
heavy oil such as 140 weight, though with the newer trunnion kits that use something other than brass, you'd be fine with EP90.
The last Reliant Rebel I had was treated by its previous keeper to grease in the trunnions and the end of the o/s vertical link simply sheared clean through as I turned in to the drive one day. It had seized solid. Fortunately, this usually happens at slow speeds but don't take the risk.
This thread, from the TDC board, shows only too graphically why grease is a big no-no.

Ooof! I meant for the bushes; I've seen enough scary pictures to use heavy oil in the trunnion itself!

Phew, that's ok then.

Don't use a lubricant on the bushes though, the rubber won't like it.
A little copper grease on the bolt shanks before you pop them through the steel sleeves is good for future dismantling purposes.

Ooo! Another thing; that's Howard's Spitfire; he lives opposite dad's flat!
