Try greenify. / Custom Kernel to OC.

Suit yourself. Non-touch: Use volume rocker, power and home button to control selection. Touch: You can tap on screen.

no, but those bloatware you remove won't restore unless you flash back the rom

I don't see any problem with it. Root will still be intact.

599 or 799 can get very good 3G phone?

Guys, can anyone of you shed some light concerning that if the phone damages the micro SD card?   

This is my second faulty card for less than 2 years now, the first was totally unreadable, impossible to format and this card last for roughly a year since my purchase. 

And then pestered my seller to get me a replacement, and got another new card in return, everything was working fine till yesterday (only after a mere 4 or 5 months  ), when it started to act up again when I'd noticed that there were corrupted pictures in my Gallery. After messing around it, I'd noticed that some files that were previously deleted were still there, so I tried deleting them again, but it reappeared again and again. It's like the card is set on a "read-only" mode or something. So tried to format it only my phone but it just won't do anything, all it does is unmount the SD card, then remounting it back. 
So tried it on my laptop again, but once I've inserted it in using both USB and microSD adapter Windows immediately tells me that the card is damaged and recommends a "check disk", but again the chkdsk utility fails to correct the problem. Formatting is practically useless at this point, all it does is also tells me that it fails to complete the action.

So request for a RMA again?

You have to add .bak at the end of the camera sound.
Use root explorer and browse to that specific folder.
Do it on your own risk,if your device bootloops don't blame me
