Two screws on the back of the steering wheel (torx IIRC) remove the airbag cassette. This lifts out, and you squeeze the yellow plug to disconnect it...
Position steering wheel straight (so you can put it back in the same position) undo the 17mm (IIRC) nut in the middle of the steering wheel...thread the nut back on a couple of turns...Sitting in the drivers seat pull hard on the steering wheel and wiggle side to side...It will then come loose off its spline taper.
Go and get tissues for nose bleed, if you forgot to thread the nut back on a couple of turns like I said!
Remove the steering cowel, several philips screws which go up through the casing from underneath...You might need to drop the under dash trim to get to a couple of the screws, but this is simple enough which just a couple of screws holding it in place. You will need to drop this to get to the plug/socket for your stalks anyway. You dont need to undo the bonnet cable clip, it will move enough on the cable.
With the column cowel removed, a couple of philips screws then secure the stalks to the ignition barrel assy...Remove the screws, follow the wiring down to the plug, cut of the cable tie that sometimes secures the stalk loom to the ignition loom so they will separate, unplug and slide the stalk assembly off the end of the column. Clock spring may or may not be supplied with your replacement stalks,this will need unplugging and comes off with the stalks.
Refitting is simply the reverse of the above.
Its really straightforwards...The only thing I can think that would be worth watching out for is making sure that your philips screwdriver is a good fit into the screws, and push hard when you try and undo them, particularly on the back of the steering wheel, and the ones that go into the barrell that hold the column cowel on. these can be quite tight, and a bad fitting screwdriver could result in these rounding sooner than coming undone, which then makes it a pain. Most of the screws on the cowel go into plastic, and come undone easily.
