Hi, don't know these areas but just to say there aren't catchment maps as places are filled by children who have a special need, or a sibling, or live nearest to the school. As factors including birth rate and sibling count vary from year to year the "catchment" varies from year to year, e.g. at our school we would not have got in this year.
Having spent a couple of years trying to move I would suggest that either you should find the school you want and rent while you try to buy or find a house you want to buy, otherwise ,as we did, you might miss the school application deadline before you find the right house, or find a house you love and check out the schools near it and your chances of getting in based on previous years (the LA will give you distances of intake in previous years.)
If going down the first route then look at school websites and ofsted reports of schools in your chosen area(s) - and choose a few to visit as no substitute for getting a feel of a school. Xmas fairs will be in early december so that's a good way to get a sense of the vibe and community feeling.
But really, my advice would be house first, and reject the house if the schools are just not right for you, go for it if the schools seem ok. Otherwise you've got a LOT of schools to research in those areas and then no surety of getting a house near the one you like best - depending how long you have before you need to apply. Also, you might get to "the school" and find it has its own problems that you hadn't foreseen, hence my view that house comes first as long as schools near are not dire.
Hope that helps - i know doesn't really answer your question but we've had a bit of a nightmare and the above is what i've learned from the process! good luck.
