Remember to NOT disenchant ALL of your quest rewards and drops. There is a new Blood of Sagaras in BfA called "Expulsion" and it is used in all primary tradeskills and it comes from using the Scrap-o-Matic 1000 to break down the piece (explation below). In alchemy you can learn to transmute it (Transmute: Expulsom, which generates 5 Expulsom per day from 10 Akunda's Bite, 10 Winter's Kiss, and 3 Anchor Weed). So some pieces may get more explusion from them that they give dust/shards.
Patience and extra gold are rather important for the mounts so it might not be best for you right now. As for the operation (Wrath and Pandaria mounts right now), you need a miner (ore is cheaper than bars), transmutation master alchemists (living steel and some time eternals for daily cooldown, titanium and riddle of steel), and potentially multiple engineers (for more Sky Golems, plus at least one gnomish and one goblin if you want to do both rockets). The best way to source Pandaria mats cheaply is to buy up Spirit of Harmony when it's cheap and check often for mats cheaper than the conversion rate (1 Spirit buys 20 ghost iron ore, 5 trillium ore, 20 Kyparite, and more). Same with Eternals (for crafting titansteel) have to regularly check and grab them up whenever they're cheap (frozen orbs can be exchanged for eternals in old Dalaran too so watch for some cheap orbs as well). I also sell Golden Lotus on the side since it goes for more than the Spirit cost. (Edit: Also should point out that at the end of the expansion everyone is bored with nothing better to do so the profits on the mounts have dipped to as low as 5k.)
Professions skills are split between expansions now, you'll have a separate skill bar for each expansion. There are still 950 profession levels in total, just that there is no one single progress bar with 1 to 950 for it anymore. Instead, there are 8 separate progress bars. (The only exception is Archaeology, because it will still have a 1-950 progress bar)
World of Warcraft’s Legion expansion has been unleashed on the live servers and players are starting to arrive at The Broken Isles to plunder its untouched reserves of gold. Some are diving into the new dungeons and raids while others are undertaking the array of quests in the vast region. See how you, too, can gain immense amounts of gold in this exciting expansion.
The best way to collect AP is through world quests, a system that allows players to complete menial tasks to earn moderate rewards. A finite amount of AP spawns on the map through these quests — generally at least 2,000 a day. I’ve likely done most of these quests close to 20 times in the course of preparing my various characters in the 45 days since the expansion launched. In some cases, I’ve replayed them as many as 50 times.

JC Panthers: Instead of breaking them all down like I did with the golem, I'll just note that currently on my server the Orb of Mystery and the Living Steel combined cost 36,000g. All of the panthers, except the Onyx, sell for 32,000g. A loss of 4,000g/unit, not including the gems. Once we factor those in, at a mean value of ~200g/unit, the loss per Panther jumps to 8,000g.
Even then, margins are much better if you start with ghost iron ore, smelt it and transmute it with a transmute master. Every trillium proc is an extra 500g free, every LS proc is an extra 3000g. If you're just buying 30 living steel there is no profit when you account for jards energy sources being about 700g a piece on some servers. 4200 Ghost iron ore is what you need. Arrange your toons with professions to max that out.
Set up TSM properly, learn it well and I can already see the power potential it has. Second is diversify your markets, learn other markets and the more you set up the more potential profit you have. Third is probably leveling alts so you have a wide range of professions ready to tackle any future opportunities for profit. Forth read patch notes religiously.

I'll typically buy cards that are < 66% of my crafting cost in unlimited quantities. If I have high stocks, i'll try to repost at 1/8 of the deck's market rate. I don't care if someone is resetting the market because i WANT sales volume and if someone is trying to a reset it's usually low enough for them to buy you out. The point here is to constantly churn your inventory and adjust down with the market.
Allied races aren’t much better. You can only earn them by grinding out reputation. It doesn’t take that long but casual players will need to invest a couple weeks primarily to it, and focusing on that grind will take you away from others, like earning gear. Each race has its own grind, but the things you do to work through it remain the same, adding to your boredom.
