1)CCD much better than cheap CMOS in respect to noise level and image quality,no need more futher post-processing with complex artificial method to smoth and soft pics,it means more RAW pic you can have.Sharp and film like.
(don't tell me that CMOS is more better! Better ask NASA why CCD is always used in camera for space mission)
2)610M is enough for most of occasion. More pixels mean more memery it needs,and more money you need to pay.is it worth?
3)Kit len is very good choise.Body will be devalue very fast for DC.
