If I just created a new adsense account and it was approved do I have to put the adds in right away. See here is the thing I was approved for Adsense and target point so I can use them my thing is will I be penalized if I don't want to put the adds in right away?
if your web site is approved, you can use your adsense code on unlimited web site. there is no second approve
you can start to put the ads anytime you like and on unlimited no. of sites. make sure all your sites are follow google TOS and you will be fine. google will not penalize you for not putting ads. but they will penalize if you put ads in the wrong way. so don't worry. anyway, welcome to adsense world.
The only thing I would look out for is making sure your site follows google TOS when you put ads on new sites.
