#1 - Sitting at a walk around event is still possible and works very well. REad the section in Ted Lesley's Paramiracles and you will see exactly how to do this. It gives you a very different structure than walking around from table to table. Allows you to have a much quieter environment AND your audience perceives you to be more than someone walking from table to table. (They DO compare to table trotting magicians and if you are set up in a little "theatre" space doing formal "shows", it IS perceived as different).
#2 - The effects one does IS dependant on the performer. Is you style a light comedic style or a serious one. There are MANY good effects that could be used and are great for close-up use. Design duplications, revealing information about the people you are working for, the list is quite endless for good effects. You just have to find what is effective for YOU through trial and error. Keep what is the best and remove what is not.
