Write strategies?

Pretty new to this forum and all this new information can get pretty confusing and I have a few questions so I can get a few things straightened out.

I have flashed my NEC 3520A with LD3520 Beta 3 and have Fujifilm DVD+R 8x - YUDEN000T02.

Apparantly the firmware tells the burning-software how to burn the media?

Does it matter if I use RecordNow MAX 4.5 (new engine and *.DLL -> http://www.dvd-recordable.org/Reviews+index-req-showcontent-id-137.phtml) or newest Nero?

Will I get the media burnt as DVD-ROM and be able to set burn-speed with both?

Do I have to specify that I want to burn as DVD-ROM with either of the programs?
