   Wow, gotta love the internet!  ;)

> pic 1 has the 2 '1.35' caps.

   Definately a tantalum (read _EVIL_!) 1uF 35V.  Use Electrolytic in 
stead if you really want to save yourself some future headaches!

> pic 2 has the '33' and '22' caps

   Yep.  Good ole ceramic capacitors.  33pF and 22pF.

> pic 3 has the '105L' caps.

   Looks like tantalums again, so it's just like the first set, 1uF.  
Again, you might want to find something else to replace these with.  
More than likely these are doing nothing more than filtering the supply 
line to the IC's, so it would do to add a beefier part here anyway (you 
really don't want these shorting out the power line!).  Again I'd go with 
electrolytic.

> does that help?

   Immensely!  Hope we've been of help too!

   Cheers,

   Tony
