Subject: Is it okay to have high HDL (outside the normal lab range)?

We all know that high LDL is not good, but I want to ask about high HDL.  The 
lab has set a normal range for HDL.  If the HDL is outside that range on the 
high side, what does that mean?  How high is "too high?"  In other words, what 
is the acceptable range?  If LDL is within the normal range but if HDL is so 
high, the TOTAL cholesterol will become high.  This can be misleading.  I 
understand that one should pay more attention to ratios than to an absolute 
number.  What should people look at - HDL:total cholesterol or HDL:LDL?  
Please advise.

Also, I would like to know what contributes to (extremely) high HDL.  Should 
one do something to change the reading?  If yes, how?  (Please note LDL is 
fine.)

Thanks.
