Well first of all, welcome to the forum,
Second, we don't discuss backups or where we get them, pm me for more on this...
As for the modchips, your gonna get different responses on that, this forum is pretty divided campwise as to which is the best, but all have the same basic function and result. Messiah is tried and true and a big fav, magic is a little easier to install if your a noob, but your V4 is gonna be kind of a hassle for u not matter what chip, the DMS has more bells and whistles but is more $. My magic works fine, but your real issue is going to be weather your old V4 laser is gonna read your cool DVD burns. Those lasers are pretty old right about now and probably will not read a DVD+, maybe a DVD- but the chances are slim, check the forum for more on this.
If you have the extra cash for a new V7 i really would opt for that with anychip, easiest install best results for reading media. Goood Luck!
