The best bow I've found is an Ebony one (After blacksmithing to Legendary Status) it is more powerful than glass.
A tip to get your smithing up as quickly as possible to 100, buy all the iron ingots and leather strips you can and make nothing but iron daggers, then sell all the iron daggers back to the blacksmith. It's not a cheat or a glitch, just the cheapest and quickest way to level up your smithing (and a number of character levels on the way.) I'm now rocking around in full Dragonbone Heavy armour thanks to all this.
The best way to farm cash is to buy a house (the one in Whiterun is the cheapest at 5k) and save everything you have in the chest. Head to Riften and go into the Black-Briar Meadery. there should be a male Elf behind the counter. Talk to him and he'll tell you how good it is working for the shop owner then you can either persuade him to tell you the truth or bribe him for about 28 gold. either way doing so will increase your speech. Once he's told you the truth you can repeat the steps as many times as you like until your speech is up to 100. if you've got a follower who can teach you a skill you can also get them to train you in their speciality 5 times per character level you can then trade with them an take your gold back off them. once you've got to a certain level in your speech, you should be able to use your perks to unlock "Invest". once you've got this perk, got to the Riverwood Trader shop and invest in his business (costs 500gold)(just talk to the guy behind the counter and choose the option) once you've done this, the guy will have around 12k so you can go back and pickup all your unwanted stuff and sell everything to this guy. if he runs out of money, wait for 48 hours and his gold supply re-stocks. I hope this wasn't too much gibberish. I'd be happy to explain it all better over mumble if you'd prefer.
