Inform the council about the brambles. You don't want them spreading into your garden. You can always deal with a barrier later eg hedge. If you plant a hedge first the brambles will get into it. Several sprays with Glyphosate weed killer will help get rid of them, but ask the council.
Clear away the junk, keep useful things, like bricks - may need them for edging beds etc later. Mow the grass. When it's tidied and mown you can see better what you have. Weed and clean the patio, then paint the workshop. Necessary to keep it from rotting. Cuprinol do good paints for sheds etc.
Buy a good gardening book. Decide what you want the garden for - veg, flowers, children's play, dining out, sitting in etc. Then take some photos and come back here to ask again!
