Also the ink dots projected on the paper ofter bleed into the dots nearby thereby killing the sharpness”

I always thought that the bleeding (if occurring: phot-paper is coated to avoid that) affects distances compareable to the size of the ink drop, that means much below the size of a “pixel” printed at 300 dpi.
I would sharpen the picture mostly for aesthetics, not for technical issues. Lightroom for example offers some predefined sharpening presets, calculated automatically for the actual print resolution (specified in the Export window).

As written in the article, RGB is often preferred because the conversion to CMYK will be performed by the driver of the printer (unless we are talking about poster and highest-end printing where the different colors layers have to be supplied by the customer).

It’s not high-end printing, but a tip: the small machines that print on the fly photos in supermarkets and similar do not accept TIFF! always bring a JPG 100% quality with you: it’s almost lossless and always accepted.
