No need to apologise, you wanted information, that is what the place is for.
Are there any small boat fishing clubs near you? If there are go and join even though you havn't got the boat yet. They are a goldmine of information, some will be good and some bad but your common sense will sort that. Offer to help out with petrol and launch/recovery, washdown, bait etc and there will be some at the club who will take you out and that is where you start to learn. You will gain valuable experience and by going on different boats will find one ideal for you.
Get a couple of sea miles and a bit of experience under your belt, check out a few different hull types and then go out and make an informed decision on which boat to buy, you will know what sort ticks the boxes for you personally by then. Everyone has an opinion on the perfect boat but rarely do they agree, what matters is what feels right for you.
Once you have an idea invest in an RYA Level 2 course. You will be surprised how easy it is and it will again build you confidence, awareness and skills.
Leave plenty of dosh in your budget to get the safety gear, and stuff to fit out your boat. If you are buying new it works out in thirds roughly, a third for the hull, a third for engine/s and a third for trailer, kit and safety gear.
