I just photographed an elopement. I tried a different workflow from what I've been using and it wasn't too painful. FWIW here it is:
1. Made my picks and did my raw conversions in Capture One with no sharpening and no noise reduction. Output was full rez 8 bit TIFF files tagged as sRGB.
2. Wrote a Photoshop action to open each image, apply Noise Ninja, apply Pixel Genius capture sharpen, and save as full rez JPEGs. These will go on a disc which will be sent to the clients.
3. Loaded the JPEGs into Lightroom and built a web gallery using one of the Lightroom templates.
4. Used Lightroom to print digital contact sheets to go to the clients with their disk of pictures. HERE
is a link to the web gallery. I don't think it took any longer than doing everything in Lightroom. Possibly I saved time because the adjustments needed in Capture One are quite simple. Also saved time by batching the noise reduction and sharpening. The final quality looks better to me than my previous method of doing it all in Lightroom. The Noise Ninja and Pixel Genius plugins are without doubt superior in quality and ease of use to Lightroom for noise reduction and sharpening.
PS. Curt there is a download from C1 which provides a pretty good video tutorial on Capture One 4. If you haven't watched it, I recommend it. I found it helpful.
