On the subject of legality, every convention is different. This is because each convention has their own agreement with industry, management style and tax filing status. Most conventions that I have attended allow clips but I know of a few where even that is not allowed. You should contact Fanime for specifics on what you can show and what you cannot show.
It sounds like your panel need not be 18+. Adults’ only panels often deal with hentai, similar adult themes or contain a lot of adult language. Most anime featuring fan service typically can be discussed in a 16+ panel. Fanime will probably ask you the age rating of your panel when you apply.
The game shows at stage zero have always given out prizes. Typical prizes there have included anime figures, DVD box sets and restaurant gift cards. I have no problems giving away prizes. At Fanime, I have always given away 100$ Amazon gift cards as a second place prize. My first place prizes have been game systems such as Xboxes and PS4s. Anime conventions typically have restrictions as to what items cannot be given away, such as cash or certain food items.
To sign up for a panel at Fanime, there should be a web page that becomes available next year. Fanime tries to make this page available in January but they seem to do so later each year. I have seen it appear as late as March. The application page will ask you certain questions such as what kind of equipment you need.
