In theory, yes, and its called Sound Check. To use it, go to iTunes -> Preferences and choose the Playback tab. Now check the Sound Check option. When you do so, iTunes will start analyzing all of your songs, and apply a positive or negative volume adjustment to them. When you play music back, these adjustments will be taken into account.

But you should know that this feature is far from perfect. iTunes determines the average volume of a track, so a song that starts softly and ends loudly may still sound out of balance with the track before or after it.

You can sort any playlist by any of the columns that you see in iTunes. You probably clicked on the Name column header by accident.

In the screen shot below, you can see that the first column header is highlighted in gray, meaning that its the current sort column. The triangle in it points upward, meaning that it sorts in order. In this case, this is the order that the songs were added to the playlist (which happens to be the album order).
