If I just stake with a Provider I also get meta bonding rewards or I have to do some other steps also?

Yes, if you stake your EGLD to any Provider you are eligible for Metabonding rewards. Metabonding will run for 2 years for every project participating in the Metabonding program. Snapshots will be daily. Every project that joins Metabonding gives 10% of the tokens supply as rewards. 5% for EGLD stakers and 5% for LKMEX Stakers. You will be able to claim tokens from all participating projects, proportional to your staked EGLD and deposited LKMEX. New tokens become available for claiming every 7 days. There is a 4 week time limit for claiming rewards.
