For a first print I am pretty excited about how well this came out. But I think I am having problems with the plastic sticking to the bed. The top side of the print looks good, but when you flip it over you can see how some of the initial layer didn't stick, the plastic got dragged around a little. Is this a problem with the plastic sticking to the bed? ie. I should use some of the tricks (like hairspray) or is this something else (maybe the extruder is too far from the bed?-I am not totally confident that I set the Z height right).
Definately a z home issue. You need to increase your value in the firmware code.
Remember increase the z home value brings the hot end further down as the value is counted from the z stop switch at the top.
