What should I buy? Frame wheels cranks bars tyres mudguards grips pedals spokes bike

Okay I think the best thing for you to do is to simply go to a reputable bicycle shop, ask the assistant to help you choose a bicycle (even though you're not buying), and need to figure out what size frame you need.

once you found the idea frame, find out what's the top tube measurement is, and use that as a base to get the idea size frame you need.

it's a little hard for people to understand what size you may without being in person.

Ahh right I see, cheers for this mate.
