Bamboo or not, it's a non-aquatic plant. They don't grow completely submerged. Same goes for the reddish plant in the 4th pic. Take them out now, before they started to rot. Read up on some easy-growing plants, and then look for those, rather than going to Petsmart (notorious for selling non-aquatic plants) and picking out plants.
If you want a decent planted tank, your next step is to get rid of that pleco.
Also, some advice for picture tanking. Don't use flash.
Read the link that WyldFya posted. Don't know how I've not seen it before, but it certainly has good info.
