Timeing Belt Guide/tips

Ok fellas

Its service time next month and I will be doing this myself as usual but this time since the focus is around 80,000 I want to also do the belt.

I will be replacing the belt with a timing belt kit and also more likely the water pump as well just when I'm at it.

Has any one got any guides/tips or recommend manuals for doing the belt as the Haynes book briefly goes over it.

also I was thinking of picking up the following tools to help with locking the timing before belt removal.

Timing Lock kit:

also want to upgrade from cordless impact wrench to more powered electric one as air compressor is no longer an option so was wondering what you guys thought of the following to aid with things like crank pully bolts ect:

Electric Impact:

and to top it all of ( :) lol!) I need a new torque wrench for doing up the bolts when fitting the timing belt. so due to reviews and not wanting to overspend I was looking at this one which I thought looked decent and should do the job:

Tourque wrench

any thoughts or tips welcome.

Thanks :)
