DNA testing

Hello my name is Edward Arce Luna I'm really new at this DNA testing,but I would like
some information. I have done DNA testing on ancestry.com I did the paternal and maternal testing I've also did family Finder DNA testing on family tree DNA . I would like to get some of my siblings, uncles, aunts,
Tested. I'm not sure which test would benefit me, Would it be the
Paternal DNA or maternal or family finder testing.?Any books or any website you
Can recommend that would give some basic information on the DNA testing
interpretations?
I have done the DNA testing on ancestry.com. Which is the paternal and maternal.
I also done some DNA testing on family DNA. Now the family Finder DNA results are somewhat different compared to the ancestry.com DNA testing I'm a little confused!
