I have just got into Hearthstone and I'm enjoying it a lot, but I want to work towards getting some better cards. What is the best way to go about this without spending money?
Should I save all my dust for a legendary? Or go for some rares?
Should I spend my gold on the arena or on packs?

The ABSOLUTE best way to improve your collection is the following:
Do your daily quests! Tim S. already mentioned this, but you should try to reset your quests that give below 60 gold in hopes of a better one.
Another way to obtain gold is by winning 3 matches. Every 3 matches you win earns you 10 gold up to 100 gold per day.
Use every 150 gold you earn to play arena! This is where my advice differs from Tim. If you win at least 3 victories in arena you will generally net at least as much as your investment of 150 gold. If you win more than 3 victories you get even more than your investment! You can see a list of all possible rewards for all possible number of victories here: http://hearthstone.gamepedia.com/Arena
If you are concerned about your ability to pick cards during the arena draft there are numerous resources available on the internet that will help guide you through the process. Just google "hearthstone arena tier list".
Arena can also be a great learning experience. There are lots of decks out there that are very competitive that are also fairly cheap dust wise. Learning card relationships and value through arena can help you not only learn how to play your decks but help you learn to develop your own! Hope this helps!

I've seen a few people disagreeing with the number of wins that I put as the break even point for arena. So I would like to defend my position on that front.
If you look at the arena rewards list you can see that it's possible to break even at 2 wins (card pack + potential reward of 40-60 gold). It's even possible, in terms of gold, not to break even at 5 wins (card pack + reward of 45-60 gold + common card). I am uncertain as to what the odds are for each item in the random reward pool, but I have noticed that gold is the most common.
So the reason I list 3 wins as the break even point is because after experiencing many 3 win arena runs I would expect my average gold return to be in the 140-145 range. Once you include the average dust earned, lets just say I have never felt bad about a 3 win arena run.
I guess my point is, on average, a 3 win arena run will net you close to the amount of gold you invested (if not the total original investment). Plus once you include the average dust earned per 3 win run, the average value you received is easily worth the 150 gold you invested.
