Upgreading Gear Solo

Hello, I'm returning player. I stopped playing when SoA came out and the account I have now was by 2box support character, so I don't have much here, but at least I have some quests/missions done and also some gils for start.

I currently farm some abyssea and I used some Bayld to get myself a what believe can be called starter set. I still need to farm Epona ring, because Rani is a *** and refuse to drop it and also brutal earring. When I finish, my TP/WS gear will look like this ItemSet 354986

I read a lot of BG Wiki and forum here to catch up, but it's really hard to understand what is soloable and what's worth farming for rare/ex items.

Also which AF, AF2 and AF3 should I get and which have highest priority to be upgraded?

I will start working on Terpsi soon. I know it's better to focus on buying HQ gear instead of getting Terpsi first, but I mainly came back to FFXI because I wanted to farm some REME and have fun with them, so please don't start explaining to me that Terpsi and only good gear will result in lower DPS than some other top daggers and great gear. I know that.

I also started working toward Twashtar. Got 50 Itzpapalotl and 13 Orthrus this weekend. I mainly do it now to get access to Rudra. I know that I can buy items for 2.5M and make WoE weapon and unlock Rudra that way, but I decided to go harder way, because I won't need to spend gils on useless dagger and I will have 90 Twashtar ready for further upgrades in the future (even if that future wont come fast).

Like I have said, I would strongly prefer soloable content for upgrades, but I guess some easy group content that I can join from /shout would work too. I hope someone can push me towards the right direction.
