I use CaptureOne LE and a lot of my shots go direct to print without going through Photoshop. I'm doing fairly informal printing at my local Costco, but they do have a printer profile from Dry Creek Photo that gives good results.
I use the Color Management settings in CaptureOne to choose the printer profile as my destination/working space, and convert the RAW file straight into the printer profile for printing. You can use the Process tab to choose 16 bit TIFF for conversions, but this might be a bit overkill if you're sending it direct to print. I haven't noticed any differences by printing direct from High Quality JPG vs TIFF. I would however use TIFF if I were going to be doing a lot of post processing on the shot after RAW conversion.
I think this is an appropriate simple color managed workflow, but I'll defer to the color management experts on the site if I'm doing anything wrong.
Hope this helps!
