 Should be fine to do with the rear clam on, although boot lid off will obviously help with access a bit. Worst part normally is the exhaust manifold bolts, which you have already done.

The star socket I bought to undo the head studs was a little short. I had to grind some metal off to allow it to fully locate on a few bolts. I have since found a longer set.

Is there a guide anywhere?  I don't recall removing the inlet in situ, it came out with the head?

well you will want access to the cambelt / waterpump cover , leave the main bolt in the alternator and it will pivot and you can remove belt , then remove the drive pulley , taking note of alignment.

ok yeah ive done cambelt before so know how to remove aux belt. i cannot remember having to actually remove any bolts from alternator tho. just slacken tensioner. so i pressume there is some fixing the alternator to the cylinder head

alternator pivots via a bracket bolted to the water pump housing  , not the cylinder head from memory. so you can leave it and the loom 

 

maybe this image helps , when I did mine. also the water temp sensor just remove the pipe . at this point the head bolts were being removed
