Well the timing marks are fail proof on the cam sprocket and crank pulley. If you used the flywheel it would be a lot easier to be off a tooth. Just crank it over a few times by hand and make sure the marks line up each time on the factory marks
ECStuning has a kit that gives you all the stretch bolts that are needed to be replaced. There are 3 on the mount that bolts to the block and 2 that bolt the other part of the mount to the chassis. That's the only ones I can think off the top of my head that needed to be replaced. Like I said anything that is slightly green needs to be replaced. FYI some of the water pump and the cover bolts (same ones) are easily stripped.
There is no need for a hoist. An extra jack might be helpful to help you get a bit of extra room (10-15mm tops )
Also both of your intake and exhaust cams are on a chain. So the camshaft sprocket aren't easily turned. Also the same with the compression you have on your bottom end with your crank moving. There shouldn't be an issue of those turning.
