CO version of this excellent PS workflow?

A fellow posted a question on photo.net about the high-quality way to resize images for printing from a lab in PS.

A fellow named "Jammer Jammer" provided the good technique for cropping with the desired resolution and aspect ratio. Then a fellow named Steve Marcantonio provided a really nice step-by-step workflow for prepping that image just right "for results like a pro."

I was wondering if Phase One could "translate" Steve's PS workflow into a CO version?

  Capture One supports constrained aspect crops. I've saved 4x6, 5x7, and 8x10 along with their complimentary portrait aspects in the crop tool.
  
  So I just select the fixed aspect that I want for a particular print, apply the crop to the image. The process tab has a setting for resolution, I just leave it at 300 dpi. I've never seen any lab or printer that couldn't just be told to, "print all of these dots at 8x10."

  Thanks, Christopher. I wasn't addressing just the cropping, as CO does a fine job with that. It was the whole workflow that described prepping a file that caught my attention. I would prefer to not use PS unless I need to do special processing, and stay within CO whenever possible.
  
  Here's the PS workflow that was in that post, with my thoughts in italics:
  
  (1) Duplicate the master file so your original remains intact. CO never touches the RAW file, so this is probably not required.
  (2) Flatten the image: Layer>Flatten Image. Not required in CO.
  (3) Convert the file to 8 bit mode: Image>Mode>8bits/Channel.
  
  4. (section dealing with resizing, sharpening, and cropping in PS snipped for brevity.)
  
  The next five steps are about using curves to bring out shadow and highlight details. Translates directly to CO?
  
  (5) Create a levels adjustment layer to compensate for limitations of papers and profiles.
  (6) Choose Layer>New Adjustment Layer>Levels .
  (7) Change the mode to luminosity. Click OK.
  (8) In the levels dialogue popup window, change the left hand OUTPUT level to 14. This will help to reveal subtle tones in shadows.
  (9) Change the right hand OUTPUT level to 250. (Note: these numbers will vary depending on printer, paper and profiles, ask your lab for advice).
  
  Now, profiling. While PS can Convert to Profile to smoosh one gamut into another, I'm not clear on how CO would do that. Here is how it is done in PS, is there an equivalent series of steps for CO?
  
  (10) Profile the image: your lab may not require a profile as long as the file has an embeded RGB color space. In the case where your lab does require a profile, ask your lab if they provide downloadable profiles from their website. Save the profile to the proper folder on your computer.
  (11) Choose Edit>Convert to Profile . In the dialog box, choose the profile you downloaded. Under Intent choose Perceptual. Make sure that both Use Black Point Compensation and Use Dither are checked.
