Congratulations!!
You didn't say what year you got and the mileage, if it's an 05 or newer w/the VVT-I engine you may want to go ahead and do the SAI bypass so you don't have to worry about the air pump going out at an inconvenient time which may or may not ever happen but for $45 and 15 to 30 minutes to install it it's worth doing now.
If your not already aware of the possible failure of the SAI pump you can read about it at the link below, for getting a bypass kit you can contact slyfox75 for getting a kit or on eBay for more $, slyfox75 has posted several time in the topic, I think his first post was #41.

Also do you know if the timing belt has been replaced, if not or you can't confirm it has it would be best to go ahead and get it done?
