New polytunnel owner

Hi,
I got a new polytunnel (well, new to me!) last year. I put in a couple of raised beds last year and grew a few veg, including some winter squash which did it's best to take over. I've finally finished weeding it all and putting in raised beds and some hanging shelves, now I'm all set to make best use of it and hoping to find out what to grow, and what not to bother with. I live in north west Devon and the soil is clay based, though I positioned the tunnel where a lot of organic matter has been added over the years, so it's quite fertile. Well, the weeds like it anyway! I've also added a lot of compost to the raised beds. Now all I need is plants.
I'm also new to forums so an idiot's guide to forums would be appreciated too.

 

What an amazing HERB... um.. dirt full of possibilities you have there!! Excited to see what you choose.
