Some questions to ask before planning a dive like this.

What level of narcosis are you prepared to accept?
What is your breathing rate?
What failures are you going to plan for?
What level of PPO2 are you prepared to accept for back gas and deco gas?
Are you planning on incorporating back gas breaks?
What do you consider the biggest risks in the dive? Narcosis? DCI? CNS? Gas?
What kind of support and backup do you have available?
Who is your buddy?
What decompression model are you going to use?
Do you want to make any changes to that decompression model?
Do you use deep stops?
Do you have a p-valve?
How much conservativism do you want to apply to your deco?
How old/fit/overweight/etc are you?

Everyone has a slightly different set of answers to these questions and your own answers will help cut down planning process.
