Coz, here goes some response to your two questions:
It is as if the warm sunlight
In some deep glen should lingering stay, <-- These 4lines I do not get.
When clouds of storm, or shades of night,
Have wrapt the parent orb away.
This stanza probably means that a ray of sunlight has overstayed its welcome. "Parent orb" meaning its parent "sun".
See the definition and accompanying encyclopedia entry for Dryad here:

Though years ago the woodman's stroke
Laid low in dust their Dryad-hair.
These lines probably allude to the fact that though the guitar is made from wood of dead trees, it brings to life the spirit of nature through its "voice".
This is not a definitive opinion, just one reader's take on the poem. I do hope it does shed some light on the possible meaning within the poem.
