Sonar X1 and timing

so a friend of mine got me going (as good friends do!) regarding timing.
specifically, regarding this: http://www.innerclocksystems.com/New%20ICS%20Sync-Gen%20II%20Pro.html
i admit i havent really been bothered too much about it, and frankly havent noticed timing problems that much. maybe this is because until final mix time, most of my tracks are 90% midi with the occasional bounced to audio track.
 
anyway, im using a fireface 800, set at 256 samples. for midi im using a midisport 8x8 with current drivers.
 
doing a little impromptu test of quantized clicks, i noted that my audio recordings are about ~350 samples behind the midi click. my asio reported latency is about 352 samples on the output side. i suppose this makes sense. if i recorded all of my midi tracks into audio, i guess this would be a non issue. or at least less of an issue. i rarely use VSTi's, but i understand that the virus TI (and many others im sure) are sample accurate.
 
QUESTION 1: what, if anything, does Sonar X1 do to correct for this?
i assumed (perhaps incorrectly) that Sonar takes care of this by delaying midi tracks by the right amount. maybe thats wrong.
 
QUESTION 2: what, if anything, can i do to maximize the accuracy of timing on my system? is there anything aside from dragging all my audio backwards by ~350 samples?
 
now of course this is not mentioning possible jitter that surely exists. again, i think that some of this is negligible. but for the robotic electronic music that im doing, im probably not paying close enough attention.
