Roots follow leeks, so you could plant spuds, beetroot, carrots, parsnips, radish etc...they don't like the soil to rich although spuds grow well in ground manured the previous autumn.
Brassica' follow spuds, so you could plant cabbage, brussels, calabrese, kale, swede, turnip, kohi rabi etc...
The spud bed will have had a good dig when you harvested the spuds so weed and mulch. So long as your compost is rotted down it will be fine on both beds.
Pea's and beans could go in either bed.
Hope this is helpful.
