Congratulations on your first password, Huinesoron!
I did post these congratulations before, but I chose quote instead of edit when trying to copy my clues to put in the first answer, and ended up overwriting my words. Not the first time I've done this.
Also, neat work, Nerwen!
1. March girl trapped between mirrored ewes’ mates yields substance fit to perfume a gondola.
2. Place of clichéd strife changes ending after an early start. Soft as elven-rope, it is!
3. Dog lit for a chewy, monotonous troll-feast.
4. Endure (though shaken) it did, at the bottom of Sam’s pack!
5. Isengard pudding and Denethor’s fate.
6. Article signed on behalf of bad pianist yields fruit (possibly resembling Laurelin’s?)
7. Projected time – jumbled – which yields this – is four o’clock.
8. Fabled cathedral (or village?) loses consecration and is initially changed for siphonable comestibles.
9. Endless chatter! Gollum provides this.
10. Wise was Sam to seek this fragrant stuff.
