The code, P0101 can be set by a number of things. Check the following:
throttle plate deposits or in the throttle bore
check for vacuum leaks down stream from the MAF
a stuck throttle position sensor
loss of vacuum to the manifold absolute pressure sensor (MAP)
poor ground to the MAP
restricted air intake tube / air filter
restricted exhaust. (Possible plugged catalytic converter)
Check these things first.
As far as the P0410, the two are most likely related. Check the following:
low air system flow
excessive exhaust back pressure (possible plugged catalytic converter)
moisture or debris in the air pump
restrictions in the air pump inlet duct or filter
This isn't an easy one to diagnose. It will require a lot of checking to see what the cause of the problem actually is. However, I do feel the two are related. The MAF that you replaced most likely was good.
