hi paul,
you've been busy! clearing it is the worst part, now i would suggest you open a beer, sit back for half an hour and admire your bare soil.....it'll never look like that again! 
you've done good, don't put anything on one of the beds, just sow your carrots & parsnips now. they prefer a poorer soil, manure applied in the same year can cause them to 'fork'.
peas & beans can still be sown if you're quick. i would put those in your chick manure bed. also bung in some brassicas plants (scrounge some, everyone always grows too many) in the one with the horse manure , as they are hungry plants.
thing is you can spend a long time preparing the soil and there's some would say it was worth it. i say you've done it, weeded, dug, bung on some maanure....now you're ready to go. i did a lot less to mine, this is my first year and i'm feeding myself every night out of mine. good luck!
