One-Eye help

Your two men aren't strong enough yet to beat One Eye before he casts shockwave (usually his first move when he gets the chance to attack), at least I don't think so. I've never really avoided One Eye's shockwave so I had to defeat it fast. If you have quick hit it helps, but you will have to take out 150,000 HP IIRC to defeat it. You could also use aeons against him (If your Yuna is weak you may need to use more than one) since they are immune to shockwave's effect. Magus sisters is more than enough to take down One Eye assuming Yuna is fairly levelled. Sandy's Razzia should hit 60,000 to 99,999 easily when you first get the Magus Sisters.

Don Tonberry is fairly easy, but he does counter attack when he is not in front of you. Basically, keep attacking him and reviving your party until he gets real close, then he will stop countering and he's also very slow, but the level up trick with Don Tonberry only works when he counter attacks.

Also tell me if you like this (Seriously want to know whether people like it or not) :-]

I couldn't stop listening to it when I first reached Zanarkand Ruins. I levelled up everyone there like crazy only because of the music and I wanted to stay in the area to listen to it. I still do.

He drops triple ap weapons. Not 100% drop rate though. Spam him until you get them for the characters you want them for. If your not strong enough to spam him take a stroll through and do the Omega Ruins. Great way to power up for the arena monsters.
