General advice from one who's been doing a lot of sewing the past few years, which I in turn got from workshops given by women with a lot more experience than I have:

After every 10 hours of sewing, change the needle, clean and oil your machine. If you're sewing silk or similar synthetics (like nylon), change the needle more often.

For hand sewing, there is a quilting accessory called Tiger Tape which will help you keep your stitches even.
