Well it appears our class is getting a spoiler for next season. In the past they wouldn't let a malformed deck lid pass tech, now we are getting an honest to goodness real spoiler.
Im not sure but the rumor is its going to be 6 inchs in height and im not sure of the length or angle. Our rules are notourisly vague. If I had to guess this is what it might read as.
Spoiler may be used, 6 inch max height.

Question 1: Where should I mount it, at what angle and how wide is wide enough.

Question 2: Im redoing my interior tin this year and what if any possible changes should I make to help the spoilers performance.

For maximum effect make it as wide as allowed (usually deck-lid width is the limit) with a 70 degree angle and a 1/2" or so forward facing lip (cheater lip I have heard it called). There are probably a lot of opinions as far as placement goes, I think it would be ideal if it were directly over or ahead of the rear wheels, but then you would miss the air coming off of the roof (I mount mine 5-6" ahead of the rear edge of the deck-lid). In general the less your interior disturbs the air the better.
I'm sure there are lot's of other opinions on this topic and I look forward to hearing them.

Wouldn't it be better to have the spoiler as far back as possible so you could get more airflow to it and also wouldn't it have more of a leverage affect on car the further back you place it. I have also heard that you want to place a curve on the spoiler for max effect.
