How exciting getting your new cat. You will always be picking up new information as you go along so dont try and overload on it now! If he is anything like my cat he will generally want food, cuddles, water, litter tray, food, warm bed, toys oh and did I mention food?
I hope Ringo settles in well as he sounds like he is gonna be spoilt rotten. Let him explore in his own time around the house. Some cats leap out the carrier and immediately want to check everything out whilst others hide for ages (days I believe) and may not eat the first day.
If you are going to let him have access to outside, keep him indoors for about 6 weeks until he has his scent around the house and surroundings which in this weather might be difficult! Lots of expert advice here for you from other forum members if you are unsure of anything - just shout up.
