The whole net gun thing made me think of that time Austin was "hunting" DX. Remember Road Dogg getting his leg caught in a bear trap ... without actually being injured? Remember DX huddling in the middle of the ring so Austin could drop a big yellow net (which they'd somehow failed to notice hanging above the ring) on them? So just remember, yes, the Austin/nWo antics could get cheesier.
As for Booker/Edge -- match should be good, but the premise, feh. I don't see why they didn't just have Edge tape one of those Stacker 2 or whatever commercials, and then (before showing the commercial) do an angle with Booker trying to get noticed by that company, only to "lose" the ad spot to Edge. It'd be a bit more believable, it'd remind everyone of the feud every time the commercial aired, and the sponsor would be happy to get a little product placement on the show itself. I guess the Japanese shampoo thing was someone's idea of a joke. I don't know why, but I have a feeling it was the same guy who came up with the Hurricane.
Jericho will be over no matter what direction they go with him. The fans have no problem cheering their asses off for him and chanting 'Y2J' and 'GO JERICHO GO!' when he's a face. They also love to hate him and boo him out of the building as a heel.
