Current GX 550 owners - questions....

[BRCinLA22]

I'm supposed to be picking up my new GX next week (current ETA). I have several questions:
1) I shopped interest rates through my bank and credit union. Currently, credit union will beat other offers by 1%. Anybody recently financed through Lexus? what is their best finance rate these days?
2) I've kept up with the forum on things enough to know I want the dealer to change a few things before I leave (because I live 2+ hours away).

• AC default to ON....I live in the swamps of LA...
• Turn off auto brake feature
• Figure out the whole 'memory seats' feature
• get a tool from the dealer for roof rack removal if/when the noise gets to be too much

Anything else I should be addressing with the dealership? Annoying features, etc.? Also - is there still no lift/leveling kit for these with a Lexus part number yet? Opinions on voiding the suspension warranty, and have it done elsewhere? I currently drive a Tundra 4x4 with lift. The low ride is going to be my biggest adjustment.
