If you want to run vBGallery you would need to purchase that and there is a sticky thread in the before you buy forum on how to purchase.
As far as vbadvanced I am unaware of what your trying to say. Neither vBGallery or Photopost are going to integrate on your vbadvanced page without hacks or mods and you can post about those in the respective mod forums for each product since those are outside or product support for each product.
There are some tutorials in the mods forum on how to make a vbadvanced photo block using Photopost.
Basically you would follow the instructions to setup inc_features.php make a new file called ppblock.php and make the contents this
Content visible to verified customers only.
You then upload this ppblock.php file to your modules directory and in vbadvanced admin make a new php block. Clean file output do not use templates and select module shell to NO.
That should do it as its pretty easy.
