Hi & Welcome!
RSOT's advice is spot on.
First of all I would say what is most important is that you read the guide from back to front multiple times - you need to know the process inside out.
I recall a great piece of advise that I never lost sight of - STEALTH means STEALTH. Think witness protection program. Oh and you need buckets of patience.
Now you can go overboard & become too paranoid - like me

But I can honestly say its easy and as long as you don't make any silly mistakes/choices you can run multiple accounts to overcome new seller restrictions.
You must not reuse images or code - change everything about your ad and if listing same product on multiple accounts, make sure that is different from your 1st stealth acc ads too.
Clean your images from data.
List slowly at first - you will be restricted to start with anyway - 10-100 items p/m.
Don't list your whole inventory from the get go. You need to appear to eb as a new seller. You will also have the 21 day hold. Id consider refraining from opening a shop straight away - but thats just me, others may have found this to be ok. Just list a few - BIN's are ok. Wait a few weeks, list a few more. Wait..etc..until you have your whole inventory back up.
I would change prices & shipping costs slightly though.
Open a bank acc from online - the sort code will probably differ from your previous - but its not too harmful if it is the same.
You cannot be linked by transfers into your account (PROVIDING THE BANK IS A GOOD ONE FOR STEALTH - Which are you planning to use?)- BUT, your name can be given to pp if money comes out of your account. So, make sure you have a fee payment plan, and refund contingency set up.
Everything is covered in great detail in the guide.
Good Luck!!
