Hi Thomas & welcome to the forum.
Some good advice above. I would definitely use the next few weeks to clear your beds of weeds and improve the soil as suggested and repair the greenhouse. I would also give the glass a good clean.
If you think you would like to use the greenhouse for starting off seeds etc you will probably want some form of staging (work benches) in there. This is often 2 tier so you have a top bench for working and trays with a shelf underneath for storage. You will also need things like seed trays, watering can, plant labels. Ebay might be your friend here.... Come back to us with specific questions if you are not sure what to get.
You will also need some tools for digging over and maintaining your garden - probably a small hand fork, a larger border fork and a pair of secateurs to start you off - hope you have a birthday coming up!
Regarding the veg I would definitely second the advice to only grow what you like to eat and would add 'and what is expensive or difficult to buy'.
Herbs are ridiculously expensive in supermarkets so if you will use them they are a great start & fairly easy. Thyme & rosemary are good with meat, coriander is a must if you like indian or asian food, and chives and parsley are good all rounders.
If you like peas I would try some - you can't buy really fresh peas. Bags of salad leaves are expensive so a selection of those would be good.
It's a bit difficult to be more specific without knowing how much growing space you have and how much time you can devote to it - especially in the summer when it will all need watering.
So, have a think about what you can beg, borrow or buy equipment wise and what you want to grow. Have a tidy and clean up (garden - not you!) and come back to talk to us some more.
Gardening is great fun - you'll have some failures but we have ALL been there - and the satisfaction of your first harvest is just great.
