Below is the config I have setup in my lab and it works great with allowing me to influence which path inbound traffic takes to my network. The only question I have is this.....
I am prepending the AS with "1 1 1" which are just random numbers i chose. Do I have to use legitimate AS numbers when prepending or can I just pick random numbers? Also, would i have to discuss this with my ISP?

You always need to prepend with your own AS multiple times. No you cannot use random AS numbers, as this could really confuse the world wide routing table. Also those 'random' AS numbers might be valid AS that belong to someone else.
Its always best that you discuss with your ISP. Some AS have other mechanism more advanced like Level3 and Localpref, via communities.
