All good choices Carl although good luck with the carrots. I couldn't grow them if my life depended on it.
If you are growing in pots,salad plants like radish,lettuse leaves and spring onion are easy peasy, quick growing and require little care other than watering.
Dwarf varieties of peas are also ideal for pot growing, bush tomartoes do well in pots and some cherry varieties will crop for Britian if you choose the one's which have a shorter growing season.
If you are growing for the first time a good book for reference is an excellent starting point. I've found gardening mags good too, the one's with a veg growing section will give tips on how to grow stuff. GW's mag has a good section.
