1) Shouldn't keep it plugged in to the charger when it is 100%
2) Should not use it while it is charging
3) It is good to let your phone die once in a while
4) It is good to turn it off every once in a while
Are any of those true? I sometimes hear people talking about these topics but they never agree on anything

One of my jobs is for a cellphone company, I also have a degree in electronics, so here goes:
Some chargers and cellphones do not have overcharging protection. The good ones do, so if you have a high end phone, and/or an expensive charger then you are fine to keep it plugged in, otherwise no, not a good idea, as an over charged battery can burst.
2 the reason you shouldn't charge a cellphone and use it at the same time, is because the charging port is a weak link in the phone, and putting stress on it, by moving it around with a cord in it, can eventually break the solder connection between the port and the board. Forcing you to either have the cellphone repaired, or buy another one
3 battery memory is not the issue that it once was, but it can't hurt to completely drain the battery once in a while.
4 turning the cellphone off does refresh it's connection to the network, and kills programs that are running in the background, so it's a good idea.1
