That being said, here's the build you asked for advice, and help on. I would have gotten it to you sooner, but I got sidetracked justifying it's very existence. Thank you,
Dagmar for helping me think it through thoroughly.

Skyrim Perk Calculator - Plan the perks for your Skyrim character before spending them!
Here's a basic plan for doing it: In Helgen, take the Ralof door, because that has the most Archers with arrows. Take all the bows, arrows, and Imperial Armor off the Captain. This will prime Radiant to kick down bows, arrows, and Heavy Armor. Swing by the Thief Stone (Believe it, or not, this gives a 20% bonus to Archery, and also Sneak.) Imperial comes with HA, and Archery, plus the daily power can stop combat if you need it before you're fully tankable.
Swing by Gerdur, and talk to her so you don't have to bluff, or bribe your way into Whiterun, later. Also, do the Smithing tutorial with Alvor, then deliver a letter for Faendal so he'll Train you up to 50 for free. Hunt around the area until it gets dark for Hides. Steal Alvor's Steel, under the end of his workbench, there will be noone to see you. Improve your Armor, chop some wood for your (hopefully Hunting) Bow, and save at least 1 Ingot. Then head west young lad to Lost Valley Redoubt. Don't miss an opportunity to pick up more Leather.
Clear them out. Sneak shot when you can, but just crouch long enough to get double damage. Spend the rest of your time upright. Get used to finishing them before they close, taking them 1 at a time, and bow punching to backpedal while you draw for another shot. Take all their light Armor, and Bows, even the Arrows if you're running low to Serpents Bluff, but grind up one of the Bows on the grindstone with the Nordskull on it. Keep improving Foresworn Armor, because it doesn't require a perk, just leather, and you'll never run out of either before you're done with Smithing.
Fight your way up to the Steed Stone. So much for being slowed by your Armor! Don't worry about Sabercats, just bow bash them, and keep shooting. Back up while bears are rearing, and keep shooting. By now, you should be getting Steel Ingots in random loot. That done, you can fast travel back to Riverwood, cut through Bleak Falls Barrow, and finally hit up Riverwood for the Main Quest. Companions are Optional, they don't really have much to offer you, but the daily power they confur comes through with (No Experience) rampages, disease immunity, and cross country sprinting with Bandits to feed on. (If you like, the Ring of Hircine is availible in the area with a Hunter's quest.)
Priorities are: Muffled Movement, and Conditioned. Do some Tanking to get your Heavy Armor up, and sneak shot to Deadly Aim/Silence. With Conditioned/Silence, you no longer need the Steed, and can easily walk close enough to sneak shot them at maximum range. These two perks eliminate all of the penalties for Heavy Armor, so now you should be, dare I say it, Superior to all the Lightly Armored archers in your game. I suggest Kajit for the Sneak bonus, the Claws also help when returning to cat form, with Fists of Steel to fight back out of the melee. It's not a stand-alone weapon, but it's a decent backup so you don't have to worry about a dagger, or the 1 handed skill.
At some point, switch from Foresworn to Dwarven Smithing to grind up faster. Don't carry it around, it will only weigh you down. Ebony is as high as you have to go to cap out your AR, then you can pretty much stop Smithing. Maybe clean out Lost Volskygge for a free Ebony Bow, make sure you can actually take it. (That guy's much tougher in Light Armor.) Then switch to Enchanting. You should be high enough level, as well as stealthy enough to do the Thieves' Guild up to the Nitengale Bow. Actually worth perking Arcane Enchanter to improve, it already starts Ebony Tier. Also, the Ebony mail is optional, it looks cool, you won't need the Muffle, but the Poison Cloak is handy in case you get rushed, or for Slaughterfishing, and the Shadow Effect is almost as good as Invisibility. If you enchant the Ebony Bow, I suggest Absorb Health, and Stamina, if you want an Unstoppable character. Unfortunately, that means the College if you don't want to wait for radiant to kick down both effects.
Followers; Faendal in 4sworn until Whiterun, then upgrade to Jenassa. She won't use a better bow, but you can get some use out of all that improved light armor, and she's a dervish with Dual Wield. Stay behind her. Once you get to Riften, pick up Mjoll the Lioness, and some Dwemer scrap while you're grabbing her sword. Forelhost for Rahgot, the Cursed Tribe for a full suit of Orcish to improve, and Volendrung. You shouldn't need a better Melee Tank, and there honestly isn't one. You might have to Assassinate her Ducky, and get rid of the body without her seeing, though.
