We are just looking at placing an elderly relative in the Poole/Bournemouth area, but into a residential home.
Prices vary depending upon CSCI ratings. As a rough guide, those with a zero or one star rating are approx �500pw and two stars �600-700pw. These rates are for single rooms. Some have shared bathrooms, some private bathrooms. This is quite a useful website for finding some homes:

The nursing homes vary in price depending upon how much nursing the individual requires.
As you would have discovered, the financial side of things is quite a minefield.
My advice to you is to speak to an independant financial advisor who specialises in just this thing. Unfortunately the things that count as 'extras' are very much calculated on an individual persons basis.
Good luck x
