Your doing great.
I would just suggest treating yourself to some good books...
Crain's Muscle World, Ltd - POWERLIFTING & STRENGTH BOOKS
Here is a good site...
Strength Online
I dont know what your general goals are but it seems like there will be alot there that you can use. If you have any sites that you would like to share please pm me.
The only thing that I would really suggest is to squat every workout. Not not heavy squatting...just light and streatch it out (except on your heavy day). What I mean by every time is just take the bar and get yourself warmed up. sets of 20-40 is good. Thats about the only thing that I would work on not seeing you work out.
Ah the other thing that I would say is change up your workouts. If you even hold the bar wider on your benches...or even as minor a variation as that then you will really help things along.
I dont lift for more than an hour. For me its really counter productive.
