I don't think you'll get all of that for only £150
I spent £400 on a Canon G9 and didn't get all that!
I think a small dSLR or micro 4/3 would do everything, but at too high a price.

Your biggest problem is the performance in low light, because a compact pocket camera will have a small sensor.
The Olympus E-P1 and E-P2 and Panasonic GF-1 get around that with a bigger sensor, and they have interchangeable lenses, but those features come at about 4 or 5 times your budget

All the Panasonic cameras I've owned have had issues with skintone highlights.

I suggest Fuji, because I thought zooming while filming wasn't important.
I don't think it is a killer feature, and when filming with my GH-1 and E-P1 I don't do it - even though they can because the lenses have manual zoom controls.

Screen resolution isn't an important feature to me either, as it's only a very rough guide to the image. More important would be an optical viewfinder like used on the Canons.
