Adjustment questions slideshow

I have a few questions about a slideshow tutorial on the frontpage:

1)I have created this slideshow with some adjustments, and it works great, but on page 1 there is also a grid (I am now using the scroller from the example):

I prefer to use this grid instead of the scroller that is used in the example.
How do I achieve this? (that also the active image is highlighted in the thumbnails). I would also like to create that the thumbs are connected to the previous and next button, so when a user clicks next for instance, the next thumbnail will be active (and also highlighted).

2)Now the slideshow does not loop, how do I change this?
