Guage Cluster Light Change

Hello, I've been looking into doing a light change in my 95 taurus SE with a tach. What I am looking for is just how many lights (blue and white) I will need. I am also interested in changing the lights most other places (headlight switch, gear indicator lights and vent switches). But any information would be helpful. Also since I don't have access to a local shop that sells the bulbs, I am looking for a good website to order from. The bulbs are the (194 blue wide angle LEDs and regular 194 bulbs). Here is the article (http://www.tauruscarclub.com/modules.php?name=News&file=article&sid=57). Thanks.
