a) i have no clue...

b) neither on this... i learnt it myself, on my own.... 1999-2002... 3 years of messing with computers... naaah.. not really...

d)i've used several Burning/Copying programs... and the most reliable one i had was (and still) NERO!!! but about making backup copies of files on cds!! i usually use Winrar 3.40 !!! i create these incridibly compressed and even highly Ultra copmpressed Solid Archives to store my data and get them split onto CDs... u can also store them without compression but make them split to fit in CDs...

but about the REAL backup programs... i can advise you of Nero BackItUp.... my Friends have been using it for quite a long time... and as i knew from them.... no problems 'till the moment

'hope i helped in a way or another...
