need new gears on my tourer. i am loathe to pay lots of money to keep it running.
so i was wondering if all this will work.
deore chainset with a 32 tooth ring. sunrace 11-42 10 spd cassette. deore spd long cage mech.

anyone know ?

Should be fine, I ran similar for a while. Only thing that hampered it was my tendency to get rear mechs from the spares bin at my LBS.

Pretty much what's on my Stooge Tony. Works fine.

Should be fine, and doesn't even need to be long cage mech. Don't know if you're meaning a new deore rear mech or an older 10 speed one, if older (36t max) then might be worth using a sunrace rear mech extender for £7.99.

I managed with just a longer B screw when I did this i would try that first as it costs pence

When you say "tourer" do you actually mean tourer, as in mostly road riding? I'd have thought 32/11 as highest gear could be a bit frustrating at times?
(Sorry, I'm a bit old-school on tourers and prefer a triple or double up front)

second the longer b-screw, I managed to clear either a 40 or 42 tooth cog on a 1x9 system with an old Deore M592 (can't remember). Worked well, suspect it would work here too.
