Read through and in the "Recommended Toons" section and for a Rogue, Warrior, and Priest it suggests Tailoring as a profession for the CD's but that appears to be an obsolete recommendation. As of patch 3.3.3 the only Tailoring CD that remains that I am aware of is the Glacial Bag which is at 7 days. Using averages from the realms I play, here is the breakdown:
Code:
64g = 4 @ 16g Ebonweave
96g = 4 @ 24g Moonshroud
3g = 1 @ 3g Eternium Thread
-----
163g Mat Value/Cost
The average AH value of a Glacial Bag is around 300g, so the above yields an increased profit of 147g per week, or for the cooldown period an average of just 21g per day. There may be other reasons for taking Tailoring (balancing professions across a large number of toons, preparing for opportunity in Cata, etc.) but there wouldn't seem to be a sufficient return on the investment of leveling a tailor at 21g per day. This may pertain to some of other the professions as well post-3.3.3, but I noticed this one having recently leveled a tailor.
For the purpose of your document, the selectiong of a character class and the profession are separate. My suggestion is to break that section into two: Character Class Recommendations and Profession Recommendations. Cover which character classes you feel lend themselves to the style of farming you recommend and which professions provide the biggest return.
One more note... you may want to post the recommended level/gearscore for farming the instances/raids and suggestions on gearing quickly. You recommended a 6.5k gs lvl 80 ret pally or dk but unless you buy one already equipped, your best option is probably a ICC25 GDKP raid or paying a guild to to carry you for a couple weeks reserving all of a certain type of loot for you. Those are more prevalent now in the lull as people wait for Cata to come out.
