You don't mean FLASH Combo?
Anyway...following ka10's advice (if you browse through the Aco subforum you'll see he's the one giving the most advice) at job level 25 you should have something like: this
You then work your way up to RD level 10 and pick Cursed Circle and Windmill for more mob control.
Concerning your gears I think they're fine, just try to get the HBP to +7 at least (if you could +9 it, it would be wonderful) so you get the bonuses and it's time to consider building up your reduction gears if you haven't already (Elemental Armors/Robes and a set of Racial carded Shields -remember that Thara Frog is best into a Valk/Immune Shield while Alice card is best on a Valk for MVP- for the other cards you can use Bradium Shields, Stone or Round Bucklers)
Work in your VIT in order to get Stun immunity, also FC depends on both VIT (HP%) and STR, but HP gears are easier to come by. Once you're able to reach 120 either in STR or VIT without compromising other stats you can go for the corresponding Temporal Boots [1] (Nope, not the enchantable ones) and SnakeWorm Skin. If you can, try to get a Medal of Honor (Aco) and a Firelock Card for the Boots once you +9 them.
As hotel stated, your role throughout TI will be either pull or tank, and the tools for that you already have them from your Champion days. CC and WM will help out with that, also try to get Gentle Touch-Energy Gain 3 to always have spheres and refresh your MS (it's actually a prereq for RD)...I personally also have GT-Cure in my build to get rid of abnormal statuses.
I think I had the same job levels as you do when I went into Mid TI for the first time, I'd say you're ready to try it. I'm currently 120/36 because I want to have at least RD 1 when I venture into High TI, but that is personal preference. Truth is, that given our role in TI parties Suras have more leeway regarding 'minimum' job levels (we pay it back with our many prereqs )
I forgot, try to +7 your weapons at least too. ka10 also recommends getting a Witch Pumpkin Hat+Alarm Mask to heal with pumpkins and that way you can use racial cards in your weapons.
