Rule number one: try everything, and when invariably some things don't work don't be disheartened. This is the difference between people who jack in the allotment after 6 months and people who keep it for years.
On a more positive note - best of luck.
As for what to do now, I'd suggest splitting the allotment into four parts.
1. For perennial things like rhubarb, asparagus, globe artichokes, fruit bushes, your greenhouse if you are lucky enough to get one off of Freecycle, etc. Cover it in manure and then black plastic until you're ready to buy and plant these things (no rush). The weeds will be smothered for the time being.
2. Dig and weed as much of this quarter as you can and get some winter greens in. Still time to grow from seed - I did mine last week! eg Kale, Chard, Spring Cabbages. (Cover with netting if pigeons are a problem in your area) Autumn peas, turnips, maincrop beetroot & carrots can still go in if you get a shoofty on.
3. Give a rough dig, cover in manure and black plastic so the bulk of the weeds will be smothered. Come October/November, you can give a more thorough dig and remove remaining weeds and then put in some overwintering broad beans, garlic and onions.
4. Manure & Cover - worry about that in the spring!
Have brought loads of books but the 'bible' for me has always been DG Hessayon's Vegetable 'Expert' book, and there is also one on fruit in the series. (They are about 7 or 8 quid each) and will get you off to a good start.
Finally - get friendly with your fellow allotmenteers (we are all a pretty jovial if eccentric bunch), not only will they provide you with loads of invaluable tips and advice but one of them is sure to have kettle and teabags on site!
All the best!
