I don't think you're in the minority.  We 
recently had a thread to show just how many guys 
would post.  I think the cel collecting men just 
don't post as frequently.  I sure notice there 
are a lot of them when I try to see the dealer's 
tables over their shoulders at conventions!  
Anyway, I'm a fan of figures too ^_^

Cels should be stored with little pressure (I put 
mine in an Itoya portfolio book and hang them in 
the closet so there is little weight on them), in 
a dark, stable (humidity, temperature) 
environment.  This way they shouldn't fade as 
fast due to the light and shouldn't become stuck 
as quickly to anything.  I believe it's best to 
keep them in plastic (polypro or mylar) bags as 
they seem more likely to stick to tissue paper or 
normal paper.

For display, there are several help pages out 
there. There is UV Protectant glass and I 
recommend going that way.  Keeping them out of 
direct light would probably also help.  You may 
want to go to a profession framer (caution, this 
can be expensive ^_^;;)  I've heard many times 
that DBZ cels tend to fade more, so perhaps it's 
best to not frame.

As for a stuck sketch, there are many ways people 
swear by when removing them.  Some people peel at 
it slowly.  Others put it in the freezer for 15 
minutes and hope it comes off.  Others try to use 
a hairdryer.  If you search the forum archives 
you might find more detail on these methods.  
However, you might end up taking some paint off 
or warping your cel so be careful.  Of course, 
over periods of time, a stuck cel may warp due to 
the cel and the paper changing sizes 
differently.  I usually just let the sketch stay 
if it's very stuck, for fear of ruining both the 
sketch and the cel.

Hope this brief overview helps!  Good luck
