Our friends over at ADA Frog made two nice videoes on how to Maximize your rewards as a delegator: https://www.youtube.com/watch?v=5fe1GFrdh8U and what you should known before delegating to a pool: https://www.youtube.com/watch?v=so06PULVdtI
Cardano.org has a lot of great information on how to get started with stake delegation: https://www.cardano.org/stake-pool-delegation/
Digitial fortress has also a good guide on how to in practice do staking and also some good recommendations for staking pools as well: https://www.youtube.com/watch?v=oQtuopB9QK0
Also to get a feeling for what Cardano is all about I think my own compilation of a few of Charles Hoskinsons words during the last year sums it up pretty good: https://www.youtube.com/watch?v=75YS1hEpZNY
For my own pool you can see the hardware I am running here:

And an intro of some of my work here:

Finally here is a small presentation of me as a stake pool operator:

If you want to consider delegating to ANP and also want to reach out to me I have a telegram channel as well.
