A friend of mine says you should handle tubes in the same way you handle halogen bulbs... with paper or any protective means to inhibit your skin (oils) from touching the glass ...is their any truth to that?

Not necessary.
The logo and number markings on some older tubes are fragile and can rub off easily [ Telefunken comes to mind ], but as far as skin oils causing "hot spots" - as with quartz halogen bulbs - on guitar amplifier tubes, they just don't get hot enough. They do get hot enough that you don't want to remove them bare-handed once they've been cooking a while.
Unless it's some type of mid-gig "emergency", I try to wait until tubes have cooled down to remove/replace/transport them. Tubes are a bit more fragile when they're hot. Other than that, business as usual.
Now transmitter tubes are probably another story entirely..

SG123 - correct ..... you can treat them as you would a conventional light blub. You are also correct on the silk screening smearing on most tubes when hot.
