I have Tech 6 boots now, but with all the rave reviews I've seen on the Gaerne SG-10s if I was buying today that is what I would buy.
Foot injuries blow, and not in a nice way. Trust me on that one. Been there, done that, got the titanium screws in my ankle to prove it. Good boots are worth it.
For a chest protector, I like the SixSixOne Pressure Suit. It might not have quite as much coverage as a regular chest protector, but it has integrated elbow pads and a back protector in it, giving it more overall protection in my view. They are a little on the expensive side, but I'd rather spend an extra $50 on gear and not go to the Emergency Room, or worse, the Trauma Unit.
