In addition to what the others have said, I'd say use PM and create
those 2 partitions for Linux (create simply unallocated space, later
format in Ext3
or Ext2) before starting the Linux installation. Then make sure that
you
select the partition for the OS in the unallocated space. Generally,
this will be selected already, but make sure you're putting the OS at
the proper place.
Don't autoformat the disk unless you have loads of space and no
preference where data goes.

You don't need to create two partitions for Linux ahead of time. You can
make the /swap and other partitions for Linux (if desired) during the
Linux installation. It is always good to have /home on a separate
partition or hard drive.
Just back up your Windows data and then use Partition Magic, Disk
Director, or BootIT NG to create a partition for Linux. This should
leave your Windows install intact. As the others have said, these
programs will do non-destructive partitioning but there is always a
chance of something going wrong so be prepared with backups.
Then boot with whatever Linux distro you've chosen. If you put Grub (the
most commonly used bootloader on modern distros - replacing LILO) on
the MBR, it will allow you to choose between Windows and Linux at
bootup.
Based on your posts, I strongly suggest that you spend some time
familiarizing yourself with partitions and Linux before you plunge
right in or you will not be successful. You should read the information
at the first link below before you start messing around with Linux. The
second link will help you afterwards.
