Here's how to build an amazing sorc:
Max Block
Enough str to bug everything on
all the rest goes in vitality.
For gear, do it this way:Wizzy/ss (res jewel or lit facet in wiz, um in ss) -> should let you hit max fcr bp (depending on the rest of your gear) and give you tons of mana/reduced damage
switch: either cta/spirit monarch (eth) OR Faceted Eschuta's with a faceted lidless.
Use all your points at 75 when you can gear (torch, anni, etc) and ALWAYS maintain max block. Think of it this way: 1 hit from a decent monster = 200hp. Say you block 3 out of 4 hits (75% chance to block) that's 800 life right there.
Using this build, and some decent gear (I can list if you'd like) I got my cold sorc to 1300 life without bo, 2.3k with self bo and having max block, max resists, 11k blizzard damage, 10.5k iceblast damage (max cold mastery), and 45% damage reduce.
Key gear to use:Shako with facet
+3 lightning ammy with str, dex or life (or maras or godly +2 sorc amulet)
Wizzy/SS
Eschutas/lidless with a CTA in stash to bo
fcr/str/dex rings preferably with resists/dex OR a bk and soj
Arachnid mesh belt
60+ life waterwalks (by far the best boots, don't listen to those freaks that are all about str bugging)
trangs gloves (cold resist > faster regen mana, especially if you pub baal)
+3 lightning ormus with um or facet OR COH OR perfect upped vipermagi with facet
Charms: high anni/storch, 9xx modded gcs (str/dex/life/fhr -> if you can afford), 9x life/single resist charms, 1 tp tome.
Skill points:Max lightning, chain lightning, charged bolt, mastery and then your choice of nova or telekinesis
1 point in warmth (it's a life saver, really)
1 point in frozen armor
The reason to use telekinesis is basically this: It's synergy bonus to energy shield is that you lose less mana for every point in telekinesis. Say you take a hit doing 200 dmg which is redirected to mana, with max telekinesis you lose maybe 30-40 mana (can't remember, been a while since I made a light sorc).
Enjoy and don't die

Edit again: At level 93, you'd have ~48k lightning damage and ~16k chain lightning damage (assuming nova instead of telekinesis) using this build with max resists. Life is all dependant on your charms really. Good charms = 1300 life, crap charms = 1100 life.
