Yeah, the timing kits seem to be all over the place, but regardless of which one people use, there doesn't seem to be a lot of chatter about failures due to cheap or inferior versions. In other words... The timing kits all seem to be acceptable. That said, there are two things that I would really try to avoid. 1) Master links, and 2) cam gears without timing marks.
I'd really prefer a continuous chain. What brand is that?
As for the bright links, you can just do what you did and it's fine. Those timing links line up every 22 rotations of the crank (11 rotations of the cam), so you really only need them once:

The timing gashes on the back of the cam gear are more of a nuisance. If everything you're putting in is new, you can/could/should be able to assume that there is no stretch and the timing is fine on hole #1, but it would be nice to have those marks. That's the Cloyes aftermarket cam gear, right?
So how new are you to this hobby? You seem to be doing pretty good for someone new?
