The selection of healing shoulders is kinda waek, I remember using tier 3 until 70. The only way you're going to get an upgrade is either to find a better BOE green/blue or get into instances. You should be able to amass enough healing gear from quests to be able to hold your own in an instance. The following filter shows all healing quest rewards you can use: clicky
I'll probably edit this post later with more information, but if you have any other questions or concerns do not hesitate to ask.

With quest blues and mid 60's dungeon blues you should be around 500-700+ heal if i rember right, thats easily enough to heal any of the normal 70 instances as long as your group knows what its doing
You might also want to look into useable +spelldamage items on any quests you haven't done yet, see here: http://www.wowhead.com/?items=4&filter=qu=2:3;ub=11;cr=51:18:110;crs=1:1:1;crv=0:0:0#0-2+1
There's a lot more +damage-and-healing gear around than pure +healing while questing, so if you have any slots with really sub-par gear, you can get items that at least contribute a bit... I levelled as a balance druid, and by mixing +spelldamage with a few +healing gear quest items, I got to 650 +healing at lvl 67 without any trouble at all, although I was wearing some cloth.
If that doesn't help, don't forget about enchants, spellthread, shoulder inscriptions, and potions. This is a little bit of trouble, but worth it. The bracer superior healing enchant ( http://www.wowhead.com/?spell=27911
) is easy to get for any enchanter, doesn't take too many materials - all stuff you can buy on the AH for 1 day's worth of daily quests - and gives a nice boost, while Silver Spellthread ( http://www.wowhead.com/?item=24275
) might be affordable on your server's AH for not too much either. If you have a nice blue healing weapon from the group quests which you'll be using for a while, you could go for a Major Healing enchant, which is more expensive ( http://www.wowhead.com/?spell=34010
For temporary buffs, these two are nice and don't seem to be too dear according to wowhead's prices: Elixir of Healing Power ( http://www.wowhead.com/?item=22825
), and Golden Fish Sticks ( http://www.wowhead.com/?item=27666

Robyn and others provide some excellent information; you should soon be well on your way to successful 5-10 man healing! Also, as far as enchantments go, you can review a previous topic
on the subject.
