Solo is where you'll get a majority of your experience now. Once you can solo in ToA, it gets much better though with the increased experience. I found myself soloing all of 65-75 in around 1-2 months. I saved my experience ring solely for BLM and made sure I used it once a day, twice on last charge when timer resets with full charge. I tried to maintain a goal for each day, around 10k seemed to work, but sometimes I just didn't have time and did just the 3k exp with ring.
Pre-ToA, you'll end up fighting mostly BST pets. Gustav tunnel has some leech pets on gobs in the lower areas, but I believe those are mostly DC-EM at your level. Those can be killed one shot with a quick AM, rest until one repops and repeat. Be careful; however, in the odd event a resist occurs, it can be deadly. I believe at your level, you can start in Pso'Xa. There is a camp with a few VT BST pets, but I don't know the exact place other than it's the 60 cap area. I tried to enter it once, but I got lost in it since its a stupid maze. I'd try getting info on that. Also, always do a quick search, usually some people already there. Perhaps you can form a party too? After that, at around 57-60, try Newton Mova. There is a couple of lower level BST pets one of which is at zone for safety. Only problem is you can only chain as long as BST pet respawns fast, but with the 1+ min respawn, you are limited to chain 3 tops.
At around 60+, I believe as soon as level 63, you can solo Qiqirn Ranger type mobs. I forget the zone name, but the first camp is in the zone off of Wajoam Woodlands. On those, for myself as a mithra, I had two full sets of gear, MP and INT/Mag.att. Because these are rangers, they will use ranged attack if you stand a fair distance from them, they only used ranged and ranged attacks will not interupt spell casts. So just nuke away with your hardest spells. Use MP set, empty it and then put in mag.att for more damage. Buffs are not entirely neccesary although on Tarus it might be, I usually used drain once midfight to get more HP and then resting MP usually got me to or near full. Make an enfeebling macro as well. Test a single mob and if you cannot kill before completely emptying MP save 60ish, then try to use sleep and if resisted, use ES+SleepII. The test is two fold, one to check resists on nukes and if you can last in a single attack and two to test if you will be resisted on sleep. Lastly, there is a danger with fighting Qiqirn, that being they tend to fight like any normal mob, but sometimes they like to run away. They're bastards like that. It's usually not an issue if it's into other type mobs or another ranger, but if it's any other qiqirn, you're just fucked. Keep RR up. You can do qiqirn to 75, just need to change areas for higher level mobs.
Sorry, didn't have time to actually organize my thoughts, my boss just got in.
