Hi Mandy,can't help with the veg.
It does all depend on what you want to grow and the space you're going to grow them in.
I'm concentrating on biennials and perennials for next year. I've sown sweet williams, sweet rocket, wallflowers, larkspurs & delphiniums. Forget me nots are another easy seed to sow now, to have flowers next year.
I don't have much luck sowing directly, probably because I don't have the time, money or inclination to deal with all the pests- and in this weather there's plently of slugs and snails about
