Looks like a great start, hopefully I'll be able to get around to posting my almost finished kit on here for review in the next few weeks.
One thing I didn't see on your list that I find very useful is a watch cap. Also, you might want to consider keeping a change of clothes (a set of utilities would be a my choice) and a pair of boots in or right next to your kit in case you happen to be dressed, oh I don't know, like a lawyer <img src="images/graemlins/grin.gif" alt="" /> (sorry, I just had to throw that in there)

Hope this helps,
Chris.
