To make your character functional while blind, you don't need to do more than have the Scent Ability and the Blind Fighting Feat. Blind Fighting lets you navigate, keep your Dex Mod to AC, and reroll Miss Chances. Scent lets you find your opponents' squares. Catfolk can get Scent as an Alternative Racial Trait. Half Orcs can get it as a Feat. Dwarves can get Tremorsense at the cost of like 2-3 Feats. Improved and Greater Blind Fighting would certainly helped, but my Half Orc Grappler with Blind Fighting and Keen Scent never felt the need to take those: Blind Fighting was enough for her.
Next, this character at level 1 probably wants Smoke Sticks, lots of SmokeSticks. When he can afford it, an Eversmoking Bottle. Hopefully, the Rest of the party will work out countermeasures against going Blind/fighting Invisible opponents, or your Blind Fighter will be the only one who IS any good in melee.
