No.
Restart
This should not damage the laptop at all, they are designed to be turned on at any time. (Unless of course the battery is dead.)
Not necessarily. There could be different components at fault when your laptop fails to charge properly - the power supply (power brick), the charging circuitry inside the laptop for the battery, and/or the battery itself (which in itself also has a circuit for diagnosis, telemetry [battery level, battery health], and overcharge protection).

When people buy a laptop, battery life and maintenance has become the important part. Then how to maintain the battery? Your new laptop battery comes in a discharged condition and must be charged before use (refer to your computer manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity.

Battery run-time on a laptop is difficult to determine. Actual battery running time depends upon the power demands made by the equipment. The use of the screen, the hard drive and other accessories results in an additional drain upon the battery, effectively reducing its running time. The total run-time of the laptop battery is also dependent upon the design of the equipment. Generally, a new Hi-Capacity laptop battery will run 30% to 50% longer than the old laptop battery did when it was new.
If you have a new macbook pro with the metal body case, no. If you have an older macbook pro, you can use a coin to turn the lock on the bottom of the laptop to remove the battery.
