Thoughts about certain skills-v
Archery- x1 Overdraw as well as Eagle Eye, Power Shot, and Quick Shot are pretty much a necessity but I'm not sure about the rest. Critical Shot could be useful and especially Ranger, but I'm not sure if its worth the investment. Not sure about putting points into Overdraw to max it out.
One Handed- As of right now I find myself using my Dual Daggers almost as frequently as my bow in combat for close quarters. The only problem is that I find combat very difficult in direct fights since dual daggers can't be used for blocking and theres no roll maneuver to dodge. The right line of perks is pretty much necessary, but I thought Paralyzation would be extremely useful in close quarters. But I also could use poisons for that... Not sure about x5 in Armsmen.
Smithing- Definitely going to take the left tree until Dragon Armor. Also, I accidentally took Dwarven Armor, so just thats unfortunate. Since I heard I can meet the Armor and Damage cap with any armor or weapon I figured it didn't matter.
Light Armor- Like the other base five rank perks above, I'm not sure if its really worth having x5 of Agile Defender.
Sneak- x1 in Stealth and the entire right tree is definitely a necessity with daggers and a bow. Silent Roll would be extremely useful for escaping dangerous situations as would Shadow Warrior, but thats alot of Perks. Pretty sure anything beyond rank 1 of Stealth is useless.
Pickpocket- Taking x1 of Pickpocket up to Extra Pockets is pretty much a necessity, but I'm not sure if Misdirection and Perfect Touch are necessary, as I don't find myself picking many pockets.
Speech- Merchant allows me to trade any items with people which is more convenient. Was also thinking of taking the Bribery perk as well.
Alchemy- x5 up until Purity as well as Green thumb is kinda a necessity as I'm going to be constantly abusing poisons once I amass a nice stock of Paralyzing, Slow, Health Damage, and other nasty effects in ingrediants.
Illusion- Illusion Dual Casting as well as the Master of the Mind line is fantastic for me because I love abusing Frenzy. Rage is also a nice tool as well as Paralysis for troublesome situations, but I'm not sure if its necessary to take extra perks simply for these spells, would love advice here.
Restoration- Necromage = Self Explanatory.
Enchanting- The only reason to invest in this is for making a set of thieving equipment and combat equipment that suits my playstyle. x5 Enchanting is pretty important as is the entire line up to Extra Effect. Not sure if the elemental line is even necessary, as I have smithing to improve my weapons damage.

Any help is greatly appreciated!

The character on which I've been messing around with Illusion is level 70 (because on the way up I leveled mostly combat skills as well as Alchemy and Enchanting) and I don't know if you want to get that high.
