If you live in UK buy a PS4. Otherwise it's up to you
No. Unless you have a UK to US power adaptor you can not use it.
About 40,000 rupees. Which is similar to the price of it in the UK.
Yes you can use your PS ID on your PS4
yes you can, but you will have to use a UK proxy.
In the UK, the PS4 is set to be released just before Christmas, on November 29th, 2013 to be exact. That same date also applies to all of the other areas of Europe.
Yes
ofcourse they do
Yeah, of course you can, but when you update ur PSP use a US updater

Use this formula: US gallons x 0.833 (or 0.83267384) = UK (Imperial) gallons
