person in all his life. <<

HunterGreen:
It does seem hard to believe. Sadly, we don't really have any strong 
evidence either way (except that Lupin wasn't the best at remembering 
to take his potion in PoA). Perhaps its not as easy to bite or kill 
someone as you might think. In PoA (although he had Sirius holding 
him back) he doesn't hurt Hermione, Ron Harry or Snape even though 
they were all right there. 

>> Who was making the potion for him before he began working at 
Hogwarts? Or did he just make sure that he was locked up somewhere 
while he was sick? Is there a hospital or clinic these people can go 
to when they need help? <<

IMO he didn't have anyone to make the potion for him before. Its very 
difficult to make and according to Lupin 'not many wizards are up to 
making it', which could be something about either anti-werewolf 
feelings or just the difficulty of the potion. Perhaps there are 
people that think the potion allows the werewolf to hide their 
condition, and that they shouldn't be allowed to do that. The potion 
might even be outlawed as a part of the anti-werewolf leglistation 
that makes it 'nearly impossible' for Lupin to get a job, perhaps a 
part of that is a requirement that werewolves check into St. Mungos 
(or a 'werewolf clinic') on the full moon to be locked in a room or 
something. 
If there are easy places to get a hold of the potion, it could just 
be too expensive for Lupin to purchase. I'm sure its a specialty 
item. Lupin would never be able to afford it when he wasn't working 
(and when he was working Snape was brewing it for free...no wonder he 
was being so polite to Snape).

>> What happened to his parents? <<

His parents could still be alive. That might be where he lives when 
he's not working. They could have been one of the people Hagrid wrote 
to when he was getting pictures for the album he gave Harry at the 
end of SS/PS (maybe that's why Lupin isn't in the wedding picture, he 
was *taking* it).

>> Why did Sirius feel that Lupin could not be trusted (before the 
Godric's Hollow attack)? Did Lupin ever wake up with blood on his 
face/hands? <<

I think even if Lupin had a 'mistake' as a werewolf then that 
wouldn't be enough to make Sirius and James mistrust him. They did 
have 'close calls' during their Hogwarts days, and they 'laughed 
about them afterwards'. No, the reason Sirius trusted Peter more than 
Lupin would have to be stronger than that.

>>Who bit Lupin as a child anyway?<<

Lupin sort of alluded that there was something more to that story, or 
maybe that's just me. His comment 'and if I wasn't being so 
foolish...' is a little odd, isn't it? (and its interesting that its 
an unfinished thought, when they were being anything but succinct 
that night).

>> (JKR better not do some weird time-travel thing where some of the
Order go back in time to fix something, and Lupin ends up being the
werewolf that bites baby Lupin as a child.) <<

I'll second that. I've had enough time-travel to last me the series.
