i am confuse when you said add dps accessoriesRings, amulet, belt can rolls mods like "Add xx physical to attack", "Increase xx% elemental damage", "Add xx fire/cold/lighting damage", "Accuracy", "Crit Multipler" these contribute to your skill dps.
support gemNot all support gems are to increase damage, there are various useful utilities like "Culling Strike" that kills everything with <10% HP instantly, useful for boss.
Support gem, as it name sounds like,
support your attack/spell skill, making them stronger and better. Or completely change behavior.Attack too slow? Add Faster Attack. Simplest example.
Obviously, because the large amount of gems, it does takes time to learn them all, and understand how to mix match them however you want.
support gem: apply to hit any enemiesEr, no. Support gem don't hit enemy. The skill that it support, hit enemy.
You augment your skills with support gem, like you add a turbo booster in your car engine to make your car faster.
And then you add black tinted, spoiler, HID light... All augment/change the basic object - your car.
aura gemIn most cases we just want to use DPS aura, because regular LIFE build really can't reserve more than 3 or 4 aura. So, make good use of the reserve.
Character build that can reserve a lot of aura are usually "Low Life" character, they reserve both mana and LIFE, and stack Energy Shield as their "LIFE" instead.
When you searching on the stash, type "Aura" instead. It will list all aura.
On your list above, Brutality, Burning Damage, Vile Toxin, Immolate, Decay are just regular skill support gems.
Curse on HitYou need to link it to a skill, so that skill apply curse when it hit something.
Eg: Lighting Arrow (attack skill) + Curse on Hit + Assassin's Mark (curse)
Usually, Curse on hit is paired with a secondary skill that can apply curse very fast across wide area.
But this play style obviously require you to play multiple skills all the time, in contrast to the "lazy" Blasphemy method.
then i should U-turn, 2-2-2-2 for all the links; sound like last 2 nodes from 4-nodes link are not that goodNo one would turn away from "additional projectile"...
Let say you uses Reach of the Council unique bow (2 projectile) + this Ascendancy (1 arrow), your skill already fire 4 arrows without using LMP or GMP.
Quiver can also corrupt with additional arrow mod, that's the most wanted corrupt mod on quiver,
and often very expensive. Shaper mod consist of additional arrow.
Now, quiver that fires 2 additional arrow is the most expensive.LMP & GMP have damage penalty, so if you can remove these gems, you got boost on dps! AND free up one socket for another DPS support!
now i alr finish act 10 at lab there and have not start anything; i just want to ask where i can farm xp quick, easy kill creeps repetitive....Hmm, find a place that you can kill fast but is still area above level 60, so you can still do the Chaos recipe. That's Act 9 though.
but my tornado shot need mana also.... i notice even now sometime i run out of mana... mean need more mana capacity if go auto aura..Your current skill cost is 21 mana with attack rate of 2.58, so you used up 54 mana per second.
Your current mana leech rate is 12 PER TARGET HIT, and mana regen 9 per second.
I don't want to go into all the crazy math, but
basically when your arrow aren't hitting anything then you're in trouble. 
Increasing dps will increase the leech rate. Do carry a mana potion in case needed.

or... use Essence Worm (unique Unset Ring)
put 50% reserve into the ring
Yep, also one strategy can use. Just make sure your resist is capped, since you don't get LIFE, resist, nor DPS mods from this unique ring.
