There is a pickup coil inside the flywheel that powers the indicators and lights. At low rpm not much power is generated so the lights are dim. Increase the rpm's and more power is generated thus brightening the lights. This is normal on a small bike especially since it has a small battery. How old is the battery? They are only good for about two years. This could be the problem on the starter, weak battery. Also, check the fuses with a multimeter. A blown fuse will kill a starter every time. The speedo problem sounds like a crossed wire connection.
