Other than putting console and/or tape emulation last on tracks and busses if I'm going to use those plugins, and a track eq (generally) post compression, what I use and the order I use it in depends on what's on the track and what I'm looking for from it.
High/low bandpassing when used (e.g. guitars, bass sometimes synth patches) I generally put first. Maybe the sonnitus eq for that job or one of the others Sonar provides or third party. Like compressors, the currently available choice of eqs, even just the ones that come with Sonar, can get bewildering. One of the great things about DAWs is we can set up as many instances of a plugin as we want until the computer grinds to a halt. The downside of all that flexibility is the sheer number of available possibilities is mind-boggling.
I generally have a bus acting as an "all purpose 100% wet default room reverb" to point track and buss sends at, again followed by eq then CE and tape emulator if used. I may also place reverbs on tracks and other busses, especially spring and plate 'verbs used for effect.
The master channel when mixing might get CE and tape, but I usually don't add eq or compression/limiting to the master bus until I'm at the mastering/project bounce-down stage. The idea being that the mixdown should result in something close enough to finished that the final tweaks are just that, not major sculpting.
I drop spectrum analysers in wherever I want to see what's going on.
Other than that I build fx processing up out of what I hope will give me what I'm after. A phaser followed by distortion, for example, is quite different to distortion followed by phasing. In general though I guess I usually follow guitar pedal routing - compression before or after filtering, distortion the same then modulation followed by tremolo, delay, reverb.
Unless I'm building a modulated or multi-tap delay, when things can get quite complicated...
I also tend to prefer resonant filter, distortion and modulation fx created by analogue hardware to digital emulation so the raw signal might well be processed before it even reaches the DAW at all.
