Newbie problems.... trackpad and tabbed browsing

Hello, well I'm almost completely new to Macs and I just booted up my new iBook G4 and installed all of the updates. Two things that I'm not able to figure out, though - the first being the big trackpad button; everything seems to require double-clicking to activate, or at least to hold down the button somewhat in order to get the computer to respond to the click. Is there some way I can make it more snappy?

Also, I'm using Safari.... why can't I get tabbed browsing to work? apple-t doesn't do anything and there is no "new tab" option under File.

Thanks.... sorry for my dumb questions... but I'm very new.

 

Okay, never mind about the tabbed bit... I figured that out.

 

Thanks, but that doesn't seem to help... I'm not sure if I'm doing something wrong or what... I guess I'll just have to get used to a heavier "click" with the mouse button... It is quite annoying, though.... I'm finding myself clicking on any link multiple times until there is a response.
