New to Jquery: two basic questions

Hello,

This is a really nice website.  It looks like jquery is great.  I have a few questions:

1) I typically code everything by hand.  I'm a bit concerned about loading a "black box" solution like jquery up to the server, without really knowing how it works.  Any thoughts on this?

2) So far, I only know how to load *one* javascript file to the server, and name it   something like: namethefilewhatever.js  Can you actually have *more than one* .js file loaded on the server and have the html web page access the two different .js files?  (Right now, I'm not sure you can allow a web page to point to more than one external .js file on the server.)


Thanks!
