Spyglasses is a good idea I can go to Heartwood, unfortunately on siege you cant sell to the npc's.
That's the reason why most older training guides typically note that they are less effective on SP, even if you don't count RoT. With RoT, it gets a bit more tedious.
Luckily the wind chime and spyglass stuff in Heartwood (and Sanctuary) are quests, not things you sell back. Just don't overload yourself too badly and make yourself an easy target for malcontents.
As for the items needing a book to make....
You can't actually MAKE them until you have read the book and are GM, but their chance to make normally, and make exceptionally, is based on a formula that uses the skill needed to make to calculate success chance(even if that is a theoretical number, if use of the skill requires 100 skill in something else).
Examples (before talismans):
Chance to make (Smith (and a few other random items for other crafters)): 0% chance at the stated minimum skill, +0.2% per 0.1 skill gained over that amount.
Chance to make (Tailor (most items, and most other crafting skills's items)): 50% chance to make at the stated minimum skill, +0.2% per 0.1 skill gained over the amount.
Exceptional chance (all skills, if the item can be exceptional):
-If skill 95.0 or less, Exceptional chance is base success chance -60%
-IF skill GM or higher, Exceptional chance is base success chance -45%
-Between 95.0 & 100.0, Exceptional chance gets an additional +0.3% over and above the amount the base chance goes up, per 0.1 skill gained.
Normal Success talisman bonuses are ignored by the exceptional chance calculation (so if you're 80% make/20% exceptional, and put a +15% make/+20% exceptional talisman on, you'll be 95%/40%, not 95%/55%).
If a basket requires GM to make, but has a listed skill of 75, it means that it is probably 100% chance to craft at GM. (50% at 75, +0.2% times 25.0 = 100%).
