soonernate,
A little tip if I might suggest this.
There is a "quote" button at the upper right corner of each post in the thread. When you want to reply to a user's specific posting and include the content of that previous post in your reply.
Simply click that quote button and the site will do it for you, giving you a reply window with the text already quoted in a nice neat little box.
Like this.

The following is more advanced, but not difficult. So you can tackle it down the line when you're comfortable doing so. We also have a "testing" section on the forum.
Once you get the hang of it, you can even remove sections of that quote, so it's just down to 1 area that you want to focus your reply on.
When you are in the "compose/reply" page, you can also scroll down to the previous posts in the thread and you'll find a quote button there as well. Click it and the site will insert that quote wherever your cursor (insertion point "I Beam") is located in the compose window above.
This way you can reply to multiple posts at once, placing yours replies in between each. This is called "in-line" replying.
You can of course edit these as well, in this way you can dissect a previous post into pieces and reply to each piece.
You'll see these techniques used all over the forum. I use them a lot!
Have fun and happy posting!
