Change Layout of Product page.

[SamGXO]

Hi guys. 
I need to change the product page layout to fill up all the blank spaces
I have provided example pictures of what needs to be done.
This is the Venture Theme.

There are 2 things i need to do:

1) Change the Slider of the Main product pictures to a clickable Gallery.

2) Change the product pictures at the bottom, from a long line to scroll down to a grid gallery.

Thanks in Advance.
