Haha I'm looking for a tank like #1 that too but they only exist in photoshop for me.
Your main problems here are trying to not disturb the existing creatures in your tank while trying to setup a planted environment. The substrate/gravel is going to be a challenge because looking at your tank video you'll want to change all that out. Something like the ADA-branded substrate or Eco Complete? I don't know what your water parameters are right now, but adding in something like ADA-branded substrate (Amazonia), it does alter the water PH a lot to make it a suitable environment for fish that do well in ph 6.5 or so (maybe less, I forget).
Your tank has lots of fish already too (I wouldn't add anymore because you have large guys in there like the gourami) so you don't want to do the substrate change that sudden. There's been a few threads already of people facing similar problems trying to setup a planted environment in an establish tank and basically you'll want to take out a few cups full of gravel and then place in new substrate. Depending how hearty and how patient you are, you could spread this out in 2 days or even longer (as longer is safer).
After you get the right substrate in there that will help plants excel, then it's up to you. The most basic things you need are better lighting, the aforementioned substrate change, and of course plants themselves. Tank picture #1 will require CO2, the other 2 I think could do well with Flourish Excel (liquid co2).
