You may only need to worry about the tranny bearing somewhere down the road as it's a failure that can happen to the 5-speed. I wouldn't worry about anything too much since the mileage pretty low (30K miles). You can go ahead to get some fluid changes (brake/oil/coolant/tranny oil) for a peace of mind, which isn't a bad idea.
If you do plan to lower the car and drive it for quite some time, then you should consider the Energy Suspension Lower Control Arm Bushings (urethane. Two small piece and one big piece on each side). Now... your only option is to replace the arm if you ask at a dealership because Toyota doesn't offer the bushing by itself. You can get those bushings replaced, but you must find a way to remove the bushings from the arm (I melted them). It's a labor-intensive install (parts are cheap), but it's not as bad since you're looking at the 5-speed (you must drop the subframe if you have auto because the driver's side bolt that goes through the small bushings won't have room to come out). When you need to replace those depends on many factors (lowering springs and wheel size plus environmental), so it's not a set thing and the big one is the piece that gets worn. I drove on stock wheels and springs for 70K miles and then lowered on coilovers. It was about 120-130K miles when I really find out the problem. One of my friends has the same car, but on 18s and lowering springs quite early. His bushing was completely shot at about 40K miles.
To show you what I'm talking about here, this picture came from the driver's side control arm. Once the arm is removed from the car, you'll see a crack on the bushing (two in this case, the driver's side is pretty worn). You can easily twist it with a long bar you can put through it. The metal part in the middle will be reused. A press is preferred to get it in.
This is the passenger's side. There's a crack already, but not on both ends. Still it's enough to cause issues.
While you're at it, replace the ball-joints too. It's held onto the arm with three bolts.
