I think all road Shimano 9-speed stuff is compatable (except for very early Dura-Ace or summat), so this should work fine.

CRC seem to have Tiagra RH shifters in stock - £60

My winter bike has Tiagra derailleurs I put 8sp Sora sti's on just before Christmas and they work well together.

Yes, you'll be able to run 9sp Sora shifters in place of 9sp Tiagra ones.
As long as you're sticking to Shimano (keeping it simple, becomes more complex if you want to mix Shim, Campag and SRAM so we'll not go there, except that SRAM cassettes are interchangeable with Shimano ones, but the shifters and mechs aren't), then the only things that care are the shifters and the cassette. they have to be the same number of speeds.
The chain should be the same as the cassette, or 'more speeds' (i.e. narrower).
The front & rear derailleurs and the chainset don't care at all, although it's easier to set-up if all the 'same speeds'.
My TT bike for instance has 8sp Ultegra bar-end shifters, 8sp Shimano cassette, 9sp Ultegra front mech, 10sp 105 rear mech, 9sp SRAM or KMC (I forget) chain, 9sp 105 chainset
- the shifters and cassette match, the rest just works.

Shimano is pretty compatible across the whole range. The road stuff works with the MTB stuff too!!
And as long as you stick to the same speed groupsets, you'll have no problems

Steve, a few years ago I had to sell my 105 STI shifters because they weren't indexed for MTB front shifting and would only only take in 2 of the 3 rings. All shimano.
