Need opinions on gear change.

I would sell the tunnel ram set up,

Why ? If they're tuned properly they work great !

If you spend the money on gears that match your tires then buy new tires, your just throwing money away on gears you don't need. I say save your pennys and just buy the tires and wheels first. Buying gears will just make it that much longer before you can afford to get what you really want.
