Inductors in Analog & Ground plane is not required. Just a 0 ohm resistor is enough. The sole idea is to differentiate the two nets. You need a mechanism to connect these two planes when you are releasing gerber filed.
Having said above, you must logically divide board in analog & digital seccion & make sure you maintain correct gnd & power planes.
Regarding placing inductor in VCC plane. Indictors are widely use. You have to make careful judgement. Blindly using inductors i some cases can backfire you.
Good Luck
