reading cap values
Olly's answered the question perfectly well, just piping in with my $0.02.
Most caps are spec'd in pF, unless otherwise indicated. Just convert the 3rd number on the cap to zeros, so 103 becomes 10,000pf => 10nF => .01uF. and 104 is 10 0,000pF => 100nf => 0.1uF. Engineers prefer to move the decimal point three places at a time, it's simple and easy to remember. Small-valued caps usually have only the pF number printed on them, so you'll see something like 47, or 680. A capacitor's physical size is a rough indicator of how to interpret the number printed on it, though watch out for the newer "supercaps" (1 Farad@2.5V in a thumbnail sized-package can be found).
It probably isn't needed on this board, but
pF = picoFarads = 10^-12 Farads
nF = nanoFarads 10^-9
uF = picoFarads 10^-6
