Javascript/JQuery Slideshow Tweak

I am looking for a java/jQuery purist to tweak a Slideshow widget used to display t-shirt line.Please review a sample version here: http://imprint.tdtg.net/slideshow/index_testversion.html

I basically need the carousel to start from the left and scroll to the right (not the center as it current stands). It would also be desirable if the next image in the carousel was not clipped (as also shown in the example). The urgency of this job is paramount and do I not personally have the time to troubleshoot this.

Feasible/reasonable responses welcome, this needs to be done like yesterday, lol.
