Staking? Buying? What should I do?

Hello all, Crypto newb here. I am pretty interested in Ethereum and have been watching it for a while. I decided I should hop off the fence and go ahead and sink my teeth in. What would you say is the smartest way to dive in?

​

I'm using Kraken. Should I buy Ethereum right now? What is going on with ETH2.0?

Should I bother with staking? What IS staking?

​

Thanks for anyone who responds ^.^
