help in positioning veg in new plot

Hi just scrounged a small area of the inlaws garden to grow a few vegetables on.And was wondering if anyone could plan where things should go(companion growing/group growing/things that should be grown next to things to keep the disease/pests down)If not to much trouble.
Plot size is about 30 feet longX10feet wide,there has been a few vegetables grown there a few years ago.I'm just in the middle of digging/weeding it over,i have noticed there are allot of worms in the soil(so i'm hoping this is a good sign).Things i would like to grow are,beans,peas,carrots,spuds,lettuce,cauliflower,swede,beetroot,and maybe a couple of other things if i can fit them in.
I have been looking at some of the threads but still not sure about this,also would like to hear of any tips i should use to aid the growth and protection of the vegetables.
Thanks  Scezy

Hi, good advice from Noshed, i would add follow a basic rotation plan ie: roots, brassicas, others. Divide your plot roughly into 3 for the different groups.
