Fletching was easy since I have a baby master tinkerer and made tons of bow cams ahead of time. From 224 just goto Shadeweavers Thicket with either a bot or a friend not on Luclin to tell you the game time. Shortly after 4PM game time kill all the mobs in the caves and dont bother looting. As a mage I was able to do this very quickly so ymmv. Then go back to where you started, by then the mobs that drop chunks of condensed shadows should be spawned, Kill them, only loot the shadows and keep up the clearing, you should be able to get 2 spawns ea of them if you kill/loot fast enough. Each clearing will yield 1 3/4 - 3 stacks of shadows depending on drop rates, 2 1/8 seems to be the common. From 224 you will need roughly 2 1/2 10 slot packs full of the shadows, so taking your time only doing it when you are bored can get you shadows in about 1 weeks time, if you really push for it you can get them all in one day... but that would be extreme.
Those shadows along with acrylia ore will get you to 268. From 268 just vendor route it to 282. Costs about 30K plat but no faming involved. After 282 you have 3 options all of which require plat and or farming. Since I stockpiled stuff making bow cams with my tinkerer I got to 296 very quick making nightmare bows which I later tributed. They trib for 3K ea so it was not long before I maxed my trib

. Nightmare bows get you to 295. Then you farm treants in Goru to get to 300. The drop rates on the treant stuff is spuratic. You'll either get a lot or very little if any per clearing. Treant stuff nets you two skill-up possibilities but also requires farming of spiderling silks and horse hoofs. From 282 skill, farming 2 stacks or buying 2 stacks of horse hoof's should be all you need.
As for what I need for finishing off research. I am gunna take my time stockpiling stuff for that as I want to get it done in one shot, or get as close as I can for it but I have a feeling I will have to talk with Xslia as she already finished research.
Things that I know off hand for research are parchments. With only a 243 skill nearly any parchment will work for the time being except used parchments. Those make combines below my trivial. Sunshard ores... tons of them. And almost any 'vellum parchment'
