You won't need to worry about accuracy until later, say mid50s or so. Even then, a life belt and sushi is enough for most mithra(as our accuracy is higher than other races)
Get Drone earrings. They'll pretty much be the last pair of earrings you buy.
I used to have the wolf mantle+1, but the Nomad's mantle is better. Costs more, but adds to your AGI. and the +evasion is nice for when you're farming/soloing.
As for rings, yeah, the +1s are nice, but are terribly expensive. Don't be ashamed to go for the normal ones. Which I believe you'll soon be looking at Amethyst at lvl36. Or you could buy a pair of Balance rings and enjoy the same +2dex right now, and use them until you either..buy deft rings, or reach lvl56 and get Fluorite rings. My recommendation would be to buy a pair of Balance rings if you can, as they will last for quite some time.
If you really are considering snipers rings, you'll need to be aware of equipment swap macros. right now, since I use life belt for meleeing, here is what my sata macro looks like.
/equip Waist "Royal Knight's belt +1"
/ja "Trick Attack" <me>
/wait 2
/ja "Sneak Attack" <me>
/wait 2
/ws "Dancing Edge" <t>
and after the skillchain, I hit my melee equip macro, which puts the life belt, among other things, back in. You can change up to 6 slots in a single macro. Like my melee equip macro, for now, looks like this.
/equip Body "Black Cotehardie"
/equip Ring1 "Fluorite Ring"
/equip Ring2 "Fluorite Ring"
/equip Ear1 "Drone earring"
/equip Ear2 "Drone earring"
/equip Waist "Life belt"
So if you got sniper's rings, I would macro those in for meleeing, then macro in balance rings when you're getting ready for the skillchain.
As for other equipment. If you can't afford Leaping/Winged boots, get Noct Gaiters +1. They will last you until you get AF boots.
