I think your choices sound really good actually. You've got a good mix of ones that are hard to get into, and those which will provide a good back up.
I know people who have applied to similar places with much poorer grades and they have been fine!
Out of your last few Unis you have listed as a possibility, I think you should seriously consider Sheffield. I went there on a visit day and have absolutely loved it ever since. Infact, I don't know anyone who has visited who hasnt ended up applying. I've also heard the Psychology at the department is quite intimate, and not too tricky to get an offer from.
