I rarely normalize at any point in the recording, unless I've made an engineering error and recorded the track levels WAY too low. For convenience then, I'll use the GAIN plugin or the Normalize plugin to get the levels hotter.

You can use the Wave L1 (not the L1+) on the master fader for your 24-bit mixdown file(s). Then you're not dithering the output. You don't need to dither unless you're reducing the number of bits.

When doing the 24-bit bounce, I don't push the limiter very hard (maybe a couple of db of limiting). It gives me more flexibility during the "mastering" session to then use the L1+ and the C4. The L1+ should be the final insert (unless you're using PAZ) on the "mastering" session.
