Dos Problemos, pleaso helpo meo

Ok, first problem is slightly in relation to a problem I'd had before, which was that the car, when shifted into 3rd gear, would have a pausing motion, meaning that it almost felt like it was braking ever second or so. Now, that's gone, and it just sits in idle when it's in 3rd, and when I push the gas, it revs to 3000 rpm before realizing it should go and engaging. However, the most recent development is that at low speeds, usually in 1st gear, if I let off of the gas it does the same thing, only it seems more severe since, I'm already going slow, so it almost stops me. It does the same thing in reverse as well.

The other problem is that turning normally is fine, however, turning tighter produces a clicking noise, that speeds up the further I turn. Any ideas? I did the o ring thing about a year ago, and about 3 months ago had a leak in the power steering return hose fixed.

Any ideas?
