Need help with my Preston team please.

I am currently on my second season with Preston North End, i haven't started my second season as of yet.
need help for who to sign. I am in N Power Championship after winning play offs last season. So obviously i need to sign a few decent average player's ready for the new campaign lol.
I have signed Mido on a free transfer, got rid of a few unwanted player's.
so i was just wondering has any one got any idea's on what player's i should sign? i would appreciate your opinions.
