To summarize:

How called the dwellers of Lyn-dun?
Starts with an "F"
Great Homer's tale of Troy,
Illiad - pdurrant
Or country of the midnight sun -
Norway - Bookpossum
What doth all men Destroy?
Death - Bookpossum

Against it man hath dashed his foot,
Stone- Bookpossum
This angel bears a spear!
Starts with an "I"
In garden-glade where Lord Christ preyed
Gethsemene - pdurrant
What spawns dark stars and fear?
Night - pdurrant

This place the white Diana rose
Ephesus - Bookpossum
Of this, Dido bereft;
Starts with an "T"
Where on four leaves good fortune grows
Ireland - Hamlet53

The Corsican was vanquished there,
Waterloo - Bookpossum
Oh, mother of all sin!

Find green the same as shiretown's name,
Lincoln - Bookpossum
Find Newgate Gaol, and win!
London - Dreams

pdurrant has 5 points
Bookpossum has 6 points
Hamlet53 has 1 point
Dreams has 1 point

There are 3 points left, pluss decoding the message. I'll give some hints to the solutions for the three last lines in the verse, but the complete solution for these lines are not needed to decode the message:

How called the dwellers of Lyn-dun?
They bear their name from a region called the fenlands. The name starts with "F"

This angel bears a spear!
The name starts with "I"

Of this, Dido bereft;
She left her home - which starts with a "T"

With this you have all the information needed to decode the message. It is possible to get four more points, but the only one able to compete with Bookpossum is pdurrant. If pdurrant has not come ut with more solutions within the next 24 hours, I decleare Bookpossum the winner. I'll be back shortly with the correct answers to the last three points, pluss the decoded message and the name of the book
