Want to starta Keto diet/training, looking for tips

So as the title suggests, I'm looking into keto as I'm currently coming close to 300lb and I'm unhappy about how I look. I have multiple questions and even if I did read about keto, I'm still confused on how to proceed. So here are my main questions:

Where to start?

How to choose your diet and where to look for recipes?

How hard is it to cut on sugar?

Should I do training too?

These are the main questions I've got and hopefully you guys will be able to help me and guide me towards the right path. I'd like to start Keto on Monday and hopefully I'll have all my questions answered by then. Thanks in advance!
