Valuable Item List

Is there such a thing floating around? I MF and pass by a lot of items since I'm mainly just looking for the things I want my own characters to wear. But I'm wondering how much stuff I've passed up that others could've wanted and trade for.
Stuff like Monarchs that can be socketed for rune words, are there other items good for collecting to use the socket quest on? I remember a flail for some runeword but I forgot what one. Or what perfect/near-perfect items should I keep? Been junking jewels lately since I don't know what ones to keep. Same for amulets and rings.
Err yeah... So there a general list of "must have" items I can browse? Something like this:
Jewels with x for mods to keep (Such as 40 ED jewels):
White/eth items to keep to socket quest (Such as Monarchs):
Uniques for cookiecutter builds (Such as... I have no idea):
Items with sockets to keep an eye out for (Such as 4 socket polearms):|||Well, white items you dont need socket Q for, you can socket with cube. So they are even more valuable then you think maybe.
IDK, when starting out, I like 2 OS and light armors for Stealth, and 2 OS wands with great +skills for making White. 3 OS shields early on for Ancients Pledge or the Gothic Ward unique is handy as well. You hit it with the 4 soc polearm too, at least for ladder players.
The 3 OS flails or Knouts for Black.
Getting into Elite items you hit it with the Monarch. I think also you would keep your eyes out for the Elite blue items for crafters - the ones that cannot be shopped or gambled. I think in this area also the 5 and 6 socket polearms become more viable than 4 as well.|||Hmm ok looking through the arreat summit trying to find the good items... I don't know about uniques and set items. I'm assuming +skill, resists, and/or crushing blow means it's good.
For other things I have...
Jewels: 40ED, 15 IAS, anything else?
Rings: I assume Resists and FCR or leech?
Amulets: +2 skills or +3 skill tree, with leech or FCR, and Resists?
Small Charms: 11 resist, 5 all resist, 7 MF, 20 life, and/or 5 FHR.
Grand Charms: 12 MF, 15 all resist, 30 resist, +1 skill, 12 FHR, and/or 45 life.
Guess white items don't matter much since socketing puts the max number of sockets on the item and just plain running without MF gear you'll find any white item you need. But what about the runewords that use less than the max sockets, like insight for 4 socket polearms. There other weapons/armor I should keep an eye out with a certain number of sockets?
Hoping to eventually collect enough worthwhile stuff to trade away for the things I do want heh.
