Yep. I went the light armour/weapons way in order to carry more loot and make more money in order to buy more training. Plus i spent a lot of time collecting ingredients to make money-making potions to afford a shit-ton of training. You don't need to spend any money on alchemy training though as making so many potions to make lots of money bumps your alchemy up to 100 in no time. Also another piece of advice, when you get enchanted weapons or armour or equipment or whatever, disenchant EVERYTHING in order to learn as many enchantments as possible. You make more money from good potions anyway, and its important to disenchant the crap out of everything to bump up your enchanting skills ASAP.
You need alchemy, enchanting and smithing and archery at 100, plus certain archery, alchemy and enchanting.perks maxed out. Plus you need 4 pieces of equipment enchanted each for archery (helmet, gauntlets, necklace,ring with fortify archery enchantment on each), and smithing (gauntlets,armour,necklace,ring with fortify smithing enchantment on each) ... put them on, take a fortify smithing potion, and then improve your glass bows to legendary, which is 300+ ... with the archery gear on when you start fighting, the damage goes up to about 540+), But i also have 4 pieces of alchemy gear (helmet/hat, armour/shirt, necklace, ring with fortify alchemy enchantment on each) as well to make smithing and enchanting potions that are incredibly powerful ... they help enormously with improving weapons and armour, plus their enchantments too. Btw when you enchant your archery, smithing and alchemy gear make sure you take a fortify enchanting potion before you enchant each item and i only ever use grand or black soul gems.
My fortify smithing potions are made with blisterwort + glowing mushroom
Fortify enchanting are made with blue butterfly wings + snowberries
Before tackling a dragon or boss i recommend glugging down a fortify marksman potion (elves ear + juniper berries). This REALLY bumps up your bow damage even more to +130%.
Also take a resist fire and frost potion (mine are at 97% resist with my alchemy gear lol) which is made from dragons tongue + snowberries + purple mountain flower.
Actually i think my bow damage goes up to over 730 damage(could possibly be more, haven't worked it out yet lol) with the fortify marksman potion, but i really only use them for bosses and revered dragons.
