1) Canon-- it's been in the dialogue of the show (Dr. Zelenka's first name is Radek, Canadian gateroom tech has the rank of Sergeant (or last name of Sargent)).
2) Almost definitely canon, but you need to squint or make deductions-- it's been in the background somewhere on the show or is a logical deduction from the dialogue that isn't stated outright (Rodney's middle name is Ingram based on a diploma and an award on his wall in Duet, Rodney only has one known living sibling based on him only speaking of/to his sister when faced with almost certain death, Radek has no children based on his discussing children in relation to his nephew and not his own children in Critical Mass).
3) Apocrypha-- it's been stated in commentaries, behind the scenes shows, interviews with or in other communiques from actors or crew, or appears on the IMDB, scifi.com or other official site (the anthropologist from Suspicion is named Dr. Corrigan according to the cast listing on the IMDB, John's father was military from his bio on... I think it was scifi.com, Radek's personal item was a still as stated by David Nykl at a convention (note there are levels of apocrypha-- Corrigan's name and John's father being military are more likely canon than Radek's personal item being a still)). Also included in this would be logical conclusions you could draw about the characters based on nothing but real world history and their own canon background (Rodney probably speaks at least some French since Canadian schoolchildren are usually taught it, Radek probably served in the Czechoslovakian military since service was compulsory when he was of age).
Fanon-- all that other stuff that tends to aggregate around characters but isn't based on anything but popularity of the idea (Major Lorne's first name is Marcus or Nick, the Dr. Kusanagi referenced in a couple of episodes is the same person as Miko who sent a message home in Letters from Pegasus).
The only ones I get particularly squicky about enough to point out are errors in true canon, though I think it's cool when I run across authors who incorporate canon-if-you-squint and apocrypha. I just found it funny that some of the canon-if-you-squint stuff has lodged in my brain sufficiently to cause cognitive dissonance when I read something different.
