showArrows: false

7 :: How to hide the carousel in MooTools?

Just like for the arrows, add this to the options:
showCarousel: false

8 :: How to hide the image information panel in MooTools?

Yet another simple switch in the options:

9 :: How to change the arrows and their position in MooTools?

Well, you have two options:

► Either change the arrows for all the galleries, by changing those selectors background values in
.jdGallery a.left and .jdGallery a.right for all the browsers
and * html .jdGallery a.left and * html .jdGallery a.right for IE6.
► Or, you could change the arrows and position for a specific instance of the galleries in your own css file (called after the smoothgallery one), with the selectors:
#myGalleryId a.left and #myGalleryId a.right
(see how it's done in for more info on the css settings).

10 :: How to change the text on the carousel tab (the "Pictures" text)?

I'm glad you asked. Since you may have different languages on your website, each instance can have it's own text. To change it, just set this option:
textShowCarousel: 'My new text'
