First long distance drive PLUS some weird behavior

I always wanted to know on how my Isis would fair when it comes to long distance driving. That day has finally came on 9th March 2009 on the occasion to visit a family in Jengkal, Pahang. The journey took about 2 and a half hour, and the statistic shows that Isis could do 14KM/L, could do 120KM/H, and would still provide a comfort ride on the road. So, it's alright to drive it once in a while for long distance.

However, this lately I find that there's a lot of squiky, dangling noises coming from the driver side dash board, from the door, and from the co-driver seat. It's not a major problem because the noise would only come after Isis was taken a trip on some bumpy or un-even road. I have this experience with my brother's Land Cruiser before, that if it's driven off road, all those cranky, thunder-roaring metal sound would come out. Probably this is a norm for Toyota car like this kind.

But there's another major thing that I'm worried about is the gear box. The gear box in my Isis is a Super ECT, gated shift transmission. The gate shift, as I noticed, would not allow me to engage the gear if the brake is on. However, when I was in stalled position, I pressed the brake, and I'll be usually able to engage the gear, but there are times that I was not able to even though I've pressed the brake pedal. What I have to do, is to shake my bump a bit to make the car move a bit in order to make something loosen, so that the gear box can be engaged. I was hoping that it will not be the gear box problem because I can't really afford to pay for any major servicing at this point.
