I have always counted a backdoor flush draw as 1.5 outs. A flush draw with two cards to come is 9 outs; a backdoor flush draw is roughly a quarter as likely to come. (1.5 may actually be too conservative, but it accounts for the times that flush cards pair the board, make someone a higher flush, etc.).
As for a gutshot draw, keep in mind that you have two backdoor gutshot draws: 9/T (in any order) or 6/5 (in any order). So 16 out of 47 remaining unseen cards will give you a gutshot draw on the turn - or 12/47, if you don't want to count the 4 that also give you a flush draw.
