What do you mean by taper the cams?

He means losen the cam pulleys so they are free to turn on the cam

In the first image I'm presuming it's showing the actual locking tool in place right?

That looks like the crank pin is on the back on the 1.4 & 1.6, its on the front on the 1.8 & 2.0 behind the cat near the gearbox end

Finally at what point would you put the locking tools in? Haynes seems to say you need to loosen the crankshaft bolt before locking?...
Should the engine turn okay to get the cams to a position that allows me to lock them?

you put the locking tools in when you are ready to remove the belt and the engine is at top dead centre( TDC is when piston No1 is at the top of the bore, note camshafts turn at half the speed of the crank so if the bar wont go in turn the engine over one more revolution ) yes loosen the crankshaft pulley before using the locking kit, leave the car in gear and get someone to press the brake while you undo the bolt.

and secondly the timing tools are not designed to hold shit in place while you torque the bolts up there is a cam pulley holding tool for that Clicky

Not being rude but are you competent to do this its not the easiest timing belt to do, and you sound rather inexperienced with timing belts
