Re cam timing, what's important is the phasing of the cams and crank. The cam turns one half turn every turn of the crank. The crank doesn't know if it's on a compression or exhaust stroke, it just pushes the piston up. The cam decides if it's compression or exhaust. If the marks line up, all should be well.

And a BIG ditto. Get the manual. You can't do this work without it. For example, it will show the proper positioning of the crank sensor. All you are doing is getting an excessive amount of practice in tearing down the front of the motor and in restraint over throwing tools...
