At 5MP you will get around 400 photos per GB storage. How many GB of free storage you will have will depend on apps installed, emails, messages etc etc.
The biggest impact the 256mb ram will have on you is it limits the types of apps you can run. Some apps require more memory.
The higher the pixel density, the higher the quality of photos and videos the camera will be capable of.
This phone will be upgraded to WP7.8 only. It will not get WP8
You should bear in mind that the 510 is the bottom end of the Lumia range. Looking at your requirement, perhaps you should be considering a Lumia 820 or 920.

Thanks for your support, but my budget is not more than 15K. I have two kids I am more concern about them. they used to take the phone whenever call comes. so till the age of 4 yrs I just wanted to stick with the basic mobile with some additional featues what I mentioned.
So what should I do??
Agree with Psychomania. 710 should be a good compromise. A WP8 device will be nice but will be a while before the prices start coming down.
