AS per point 1, your PEAR path is c:\xampplite\php\pear\
However, your path is pointing to \xampplite\php\pear\PEAR
Putting the two one above the other you can clearly see one is too long:
c:\xampplite\php\pear\
\xampplite\php\pear\PEAR
Your include path is set to go one PEAR too deep into the pear tree. The PEAR subfolder of the pear folder includes the PEAR component. You need to adjust your include path up one level.
(you don't need the c: by the way, your path is fine as is, just too deep)
