Working on Secret Fish and planning for the week

I'm trying to make more of an effort to clean up the quests and achievements that have been sitting around for what seems like forever on the right hand side of my screen. To that end, I spent an hour before bed and an hour before the weekly reset working on Secret Fish and Where to Find Them - my wife already has this achievement which she described as "a pain" and I'm both jealous of her awesome ball of the ocean toy and tired of seeing the achievement listed under the ones I've been tracking as a reminder.

Anyway, I picked up a dozen or so of the fish I'm currently missing and I only have nine left. I got a nice surprise right before the server reset, fishing up a Mimic Octopus for the Pandaren Angler achievement (and a few Nat Pagle rep). I also managed to get another Tol Barad win randomly - now at 23/25 wins for the last achievement I need for that meta.

Plans for the next week:

1. It's Timewalking this week, so I want to do at least one Timewalking dungeon on both my main and on an alt alliance mage for the 500 tokens - gotta get those mounts!
2. It's apparently Firelands Timewalking. I still need more Firelands rep, so I'll be doing that too.
3. The usual Molten Core run for rep and my last armor piece. I've got this down to under ten minutes and I use all three guild banners for extra rep.
4. A Throne of Thunder run for rep and missing set pieces. Hopefully I'll hit exalted here.
5. I'm going to farm some Timeless Isle rares and Emperor rep. I feel like I'll hit exalted long before I get all the stuff for the horribly difficult Going to Need a Bigger Bag so I'm not stressing about this one too much.
6. Finish Secret Fish. I have the schematics to go to The Other Place in Mechagon whenever I wish, so the occasional nature of the Chromie quest isn't an issue here.
7. I'm aiming to do a BG a Brawl and an Epic BG every day to both gradually work on my PVP achievements and to get some more Mark of Honor to finish up my "appearances" achievements.
8. After all that, I'm not sure. I should probably work on Broken Isles pet dailies since that's a long grind and they only have a couple up at a time but I find it really tiresome to have to travel all the way to every trainer and, more importantly, I can't yet tell at a glance which quests yield relevant trainers and which are with ones that don't have achievements. I should print out a list.
9. Daily Naval Missions for the "1000 Naval Missions" achievement. Blah.

All of the above mostly feels like housekeeping. I need to find a new meaty set of achievements to work on next. Is it finally time to go through all the old Dungeons and Raids achievements that I'm missing? Cataclysm looks like it's full of quick wins:
