It is possible to get 18 commendations per day plus 3 commendations per week, bringing the time to get the mount down to about 11 days of luck and persistence.
First, make sure you are doing the Victory in Tol Barad quest each week. You don't have to be a PvP master to do this quest, just make sure your in the zone during the battle and (optionally, for the sake of your realmmates) assist however you can.
There are then a total of 18 daily quests for 1 token each that you can do. However, reaching all 18 will require you to cycle Tol Barad victories.
First, make sure you are doing the 6 dailies outside of the PvP zone. These will always be available and never change for a guaranteed 6 tokens per day.
Now, when your faction controls Tol Barad, there is three more quests available in the PvP zone guaranteed:
Each time Tol Barad resets, there will be a second NPC quest giver in the PvP zone who rotates available quests. There are 3 different sets of 3 quests, all involving the area outside of Baradin Hold. This guy will randomly cycle each victory you get, so it is pure luck.
So that is:
- 6 Commendations each day for quests in the PvE side of Tol Barad
- 3 Commendations in the PvP side of Tol Barad
- 3 sets of 3 Commendations randomly chosen in the PvP side of Tol Barad
18 commendations per day, plus 3 commendations per week.
(Side note: don't be afraid of the "PvP" side of Tol Barad, no actual PvP goes on when the battle isn't live, the opposite faction has no purpose to be there except for the occasional griefing).

Picking up specific green-quality items is extremely difficult. While green items in general are common, there are many different types, so you will have a tough time farming any particular piece. Also, since many low level players are actually alts, many of them don't see much value in putting these items on the Auction House.
If you cannot find similar items in blue- or purple-quality* (eg. you can easily farm Acidic Walkers instead of Shimmering Boots), I'd recommend both farming and searching the Auction House. You can search the Auction House efficiently by using shopping lists included in auctioning addons such as Auctioneer or Auctionator.
As for farming, you'll want to keep a few things in mind:
In terms of what you should kill, I recommend doing your best to farm for as many pieces at once that you can. Each of them has a level range of mobs that they drop from:
So, the sweet spot for farming these items is by killing mobs that are level 22, broadening as you find items from either extreme of the level ranges. All of the items show that they have been dropped from mobs at level 22 in Duskwood, Hillsbrad Foothills, and Wetlands. I recommend that you set your Hearthstone in one of these zones and dedicate an hour or so each day to farming kills (and checking the Auction House) until you get your items, as I did.
* If you are interested in searching for compatible/acceptable blue- or purple-quality items to farm instead of green-quality items, the MogIt addon may come in handy.
