CO Trim is high - will globally richen the fuelling throughout the rev range. I'm not sure what your fuelling values are under load but if it can be turned down to nearer 0 with a +/-10 tolerance thats the 'correct' place for it for mapping etc.

Also, the ignition advance seems quite high for idle, is the engine low compression?

Being slightly picky - I used to set the TPS to -0.30 on IAW and idle speed to between 900-950rpm.

Obviously every car is slightly different and you need to use what is correct for your application, but the info mentioned above was just what I used as a rule of thumb!
