Photos to DVD

I am an extreme newbie to this so please forgive me in advance. I am trying to create a DVD of several photos that I have scanned onto my computer. I have downloaded DVDSanta and it appears to be what I am looking for. I have 2 questions that are kind of related.
1. Is DVDSanta the best program to create the photo dvd?

As for the 2nd question, DVDSanta lets you add a song to the photo slide show. I would like to add just small portions of different songs to the dvd - such as 30 second parts of songs, not the entire song. I have a program that can split off small protions of songs but it will have the song start and end abruptly. I need a program that will let me split off approx 30 seconds of the song but will fade in at the beginning of the clip and fade out at the end of the clip

2. Is there any program that will let me split smalled portions of music but will have it fade in and out?

I am not sure if this is the correct forum so please forgive me. Any advice is greatly considered.Thanks
