Thanks for your help all.
I ordered the chems today, Ag were very helpful indeed.
I have a whole bunch of negs to catch up on (35mm and 120) so should be able to get some results soon but I don't have a scanner to post the results right away but I will do my best to get some examples up in time.
I already have some 8x10" Supra Endura so I'm not after more paper just yet -- but I might be looking for larger stock at some point.
My next purchase will probably have to be a flat-bed for scanning the prints though. (I figure this is a reasonable way to bring the photos into the digital realm short of blowing a non-existant in my case pile of £2k on a Nikon Coolscan -- plus I get the fun of working in the darkroom)
