I'm having problems with my iPhone

When I'm texting my friend who has an android phone sometimes their messages come blank & at first I thought they just sent a blank message. I asked for them to resend it & it still came blank. Why is that? & secondly I have a friend who has go SMS & can see & send emoji so when they send emojis from their android phone to my iPhone I can see it perfectly fine.

Connecting my new iphone to itunes

I've already got an itunes account for my ipod touch. But i'm already stuck on the first step which asks me if i either want to back up my ipod touch contents or set up as a new iphone. Which should i choose? What will happen if i choose set up as a new iphone? Will all my previous contents disappear? I don't want that to happen because i have a lot of music in my library.
There's another problem, I don't mind sharing my music between my ipod and iphone but i don't want to share my photos between the two devices. Sorry for the complicated question.
