Also, Routine one I want to rest 45 seconds between sets. On routine 2, I want to rest 3-5 minutes.

It's a pretty good routine, but if you are going to do an upper/lower body split you may want to go ahead and do both pushing and pulling on your upper body day. I've trained this way with good results.

I'll keep the in mind.

Ya KW has a good point - implement some push/pull if you're doing upper and lower body splits. I've also done routines like this, great pumps and great results!
Good luck with your routine man, you should have good results -just make sure your diets spot on!
Cheers.
