Monetize an app

Hello,

So i started using corona a month ago and a made a puzzle game with 100 levels and i want to publish it to the android store.

I am thinking of doing a lite version with 25 levels, and the pro version with all the levels.

My questions are : - Is this a good strategy?

                              - What are the best Corona plugins to use to monetize?

                              - How to advertise the app?

                                

Any tips will be helpful,

Thank you,
