The way I leveled enchanting was to use all of those leather bracers I had crafted from leveling smithing as a base item and then just enchanted them all with +archery. Doesn't take to long and can be done at a consistant rate if you careful in leveling it to avoid overdoing it. Soul stones are easily found in any dwarven ruin, and with a soul trap weapon as your main you can easily level it as and when required.

Plus there is a quest for the master level enchanment trainer in Markath to help get it up to higher levels faster if you so choose.

Conditioning is a decent perk but Steed Stone is the better choice and allows you to use a couple more perk points on more useful perks. I actually prefer the Light Armor Perks much more powerful and easier to get the No Armor weight perk.

The iron daggers trick is when you powerlevel enchanting to max level. It's usually done when players powerlevel alchemy and smithing at the same time.

You'll be able to one-shot everything from what I've heard, but it would make the game rather boring, IMO.
