I havn't used cdrdao myself but looking at the man page it tells me it 
defaults to "full paranoia" when ripping.  If it was not for your 
"skipping" problem I would have suggested that disabling paranoia might 
speed things up, however...

My approach to a dodgy cd would be to first give the disk a good polish 
then use cdparanoia in batch mode "cdparanoia -B" to rip all the tracks 
from the cd to wav files and look at the output on the command line to 
find out where the program is having a hard time.  You can then listen to 
parts of the wav files to check if the errors are audible before buring.  
It's time consuming but at least it saves you wasting cd blanks.

Are you by any chance trying to copy one of the - so called - copy 
protected cds that are around the shops nowadays.  This could be the 
cause of your errors - see http://ukcdr.org/issues/cd/ for more info.   
There might be some information on the cd cover telling you about this 
but you will need very good eyesight - it's not a "Parental Advisory" 
sticker!
