My vets protocol is after 8 weeks then 3 weeks inbetween each vaccination and then a week after the last is recommmended before pup can go out on the ground.
As for socialisation I use a babysling one that fits like a sling for a broken arm and find it really helps in getting around with a large lump of puppy in your arms, it is surprising how many places you can get to with a little planning.
Unfortunately one of our local garden centres, my favourite as it happens , has banned dogs due to hygeine reasons so I am now lurking in other places ie outside supermarkets, schools, may try a very short bus jorney too.
Hope you are enjoy your new pup as much as I am mine
