Damn, Im in a very similar position to you. The numbers are almost identical! Out of curiosity what weight are you doing on the leg press? Its probably irrelevant for squats, but would be good to know. After the squats, I am up to 320kg for 3 reps (300kg for 5). This has increased a lot in the last month but the squat hasn't at all, which is very frustrating!!!!
On the squats, as soon as I go for 110kg, when i try to go low, I start to fall forward!!! Shitting me big time. I have to get some decent advice on how to squat properly. Mind you as per above advice, I'm doing for 5x5's now starting at 60kg and going from there.
