The lock button isnt working correctly because of some bad soldering on the new glass. it is where the home button flex joins to the flex on the glass and eventually down to the connector to the main motherboard. it is possible to peel it apart gently and rework the solder connections if youre feeling skilled. The erratic touchscreen response may be due to exposed digitiser connections at the bottom of the glass. normally, i use heatproof tape to cover the row of touchscreen connections on the bottom left when looking at the back of the glass . Once this is done, another piece of tape over the exposed components of the home button flex part will prevent a home button actuation when you put pressure on the bottom of the ipad.
