Just an update on this for those with similar problems.
The gearbox is out and harvey your diagnosis is absolutely spot on! HARVEY WE ARE NOT WORTHY!!!
You can move the input shaft side to side. Also I drained most of the oil out before I removed the box, when I got it out I turned the box on end to make more room in the garage. The remaining oil came out via the input shaft; presumably the worn bearing has caused oil seal failure.

Please, this is probably a stupid question, but do you simply remove the clutch withdrawal race housing from within the bellhousing to access and change the primary pinion bearing or do you need to split the bellhousing from the gearbox casing for access?
Also, if you do need to split (and I imagine you do, if only because the forward end of the mainshaft must also be held by some sort of bearing in the back of the bellhousing), could you do so under the car and yet leave the bell housing in situ (just removing the gearbox casing and contents from the car)?
Honestly, it's not that I'm lazy - I just find that the less I dismantle, the less there is to go wrong!!
