Need some advice! i want my yaris asap :)

[yup101]

I need to get this car as soon as possible (possibly by next week). I have a several questions regarding 2007 yaris sedan automatic. here it goes..

1)I want power lock, power window, and FM/AM radio option. Can i get these seperately without power package?

2)Base on admonds.com
msrp+ power lock& window+ delivery charge = 13,920
Invocie + power lock& window+ delivery charge = 13,030
what would be the best deal with these price?

3)How should I deal with dealer (this is first time I am buying a car)? Do I need to print out the TMV price that i got from edmonds.com and show to dealer and possibly go from there?

4)Which site is most accurate site to see the car price?

Thank you so much for you guys support!!
p.s I am going to the dealer tomorrow :)
