1) depends on if you are imbuing for profit or needs, they say imbuing weapons has the highest chance of usable mods, but the market is completely flooded with martels already (same with ornates, tons of them posted for sale)
imo, imbuing grim helms at level 84+ so you can get the red life mod is the most valuable, since the only monster that can drop red grim helms is hell diablo. Back when i played, i was getting a red grim helm about 1 out of every 3 imbues that i did, and also got some pretty sexy brown ones along the way.
obviously dont imbue normal items since they can be gambled more easily. if you don't want to wait until level 84, then i would imbue some mage plates in the mid 70's
2) for my ES sorc I have always used 2 sojs and mage fists, I was never a fan of frostburns for a couple reasons. A) its hard as fuck to get a +2 10 fcr priz ammy.
I like the 25% mana regen and +1 to warmth (12% mana regen) that mage fists give, which makes them nearly as good as frost burns. But either way works.
3) Bone necro with some levels in corpse explosion and amp damage or lower resists. ( 20 bspear 20 bspirit 20 bwall 20 bprison, rest into CE and curse of your choice) hell you could even max CE at the cost of some damage honestly.
Javazon either pure lightning skills (godly with lower resist curse) or poison/lightning hybrid for solo play capability is nice too
/edit
I disagree with the guy above that says to use a precast staff for pvm, because its annoying to do with without wepeon switch in classic every game, and also not important for pvm.
if it was a pvp sorc, then yes get a precast staff.
/edit
Also, imbuing grave wands at level 8 makes it possible to get +2 necro skills as well as + to skills like skeleton, amp damage, corpse explosion, bone armor.
Things that cant normally spawn. if you wanna have some real fun
I'm sure theres similiar rules for staves and scepters, but i never calculated them
