Newb needs 08 sedan data+maintenance manual

[nik danger]

Hello Planet Yaris!

I just bought an 08 sedan,5 speed,134,000 miles,small, linear,bubbly rust strip on rocker panel below driver door about a foot long.
Bought it from the original smoker owner.
Car has pep for a 1.5L motor,(Just not up long hills)

Live in Lancaster County ,PA (Dutch Country...Amish,buggies,etc.)

Details:
Charcoal color,(Matches the intense smell the tobacco addict who I bought it from left inside)
Has tachometer,crank up windows, no central door locking system,single CD player,rear window defrost with built in radio antenna, no traction control,no cruise control,no ABS.

As there is no exterior badge indicating trim level, I suspect I have a Base model.

Questions:
1) What trim level do I have/what is the sub-model?
2) Where can I get a maintenance manual / guide ?
2a) Would anyone care to copy one and send it to me?
3)How is the motor referenced,(Manufacturer alpha numeric number)?
4)What is the official Toyota color?
5)The 60/40 seatback release knobs,(one is damaged,the other missing) - where can I get replacements / installation diagrams?
6)Does anyone have any good ideas on how to add an extension to the driver side seat rails- I'm 6/5" and a little cramped ? I know this will involve some fabrication.

Please and thanks,
Nik
