Reproducing these type of reflections totally depends on the quality/experience of the printing house you will be working with. To stay on the safe side I would recommend going without it for the print media and keeping shinny reflected one for the digitial media like your web site, power point presentations, word, excel etc.
As for the other stuff you mentioned above I do have experience and you can visit my site to see some of my work at www.logoroad.com -it says Corporate ID Package for a forex company on the home page. Please also check to see how those 3D designs with reflections and all came out right here
