Sounds like LDS-1 isn't very helpful. Maybe you need to end up with a LDS-3.
If you are being pushed face first at the surface maybe you are overfilling your BC. You don't have to have it fully inflated to stay bouyant at the surface. Also maybe your tank is too high, pushing you forward and also that might explain the floating feet. 40 lbs of lead does sound like a lot. What kinda suit are you wearing and what's your build (if you don't mind me asking). You will find over time that as you relax and get comfortable in the water that you will need less weight.
