I want to be able to use an older LCD monitor as a second monitor with my iMac.
1.. Is this possible?
It could be. You don't identify your specific model of iMac.
2.. The monitor I have only uses a parallel connection into the monitor.
Do you really mean the old PC-style parallel connection, either DB-25 or Centronics style?
I'm not aware of any LCD monitors that have a parallel port as their primary connection. More likely what it has is a VGA connector:
Your iMac may have come with the proper adapter. If not, the particular part you need depends on the model of your iMac.

Your iMac is an Early 2008 iMac. According to the specs
it has a mini-DVI output port with support for DVI, VGA, S-video, and composite video connections via adapter.
What you described above sounds like a VGA cable, so you woudl get a mini-DVI to VGA adaptor, such as the following:
Of course I am only going by the descriptions you are giving. If I accessed the wrong iMac specifications, or if I guessed wrong at the LCD cable you are using, then the adaptor could be wrong as well.
Your mileage may vary. Objects are closer than they appear in the side view mirror.
