Some things I'd like to add to Ryan's excellent post: Mark the current position of your three bolts in the strut tower so that you can reassemble it as it was. Check your tie rod ends for wear while you are doing this job. When it comes time to re-attach the brake line bracket, take a pair of needle nose Vise-Grips and clamp the bracket in place before trying to fit the bolt through it. In addition, slobber some anti-sieze on the threads of your gland nut before reassembly. The next lucky contestant that gets in there to do this job (who knows?, it may be you) will appreciate the gesture. Check the condition of the rubber in the strut mounts while you've got things apart. They should be in pretty darn good shape. If they are obviously worn or obviously torn, get new good ones. Tasca Volvo I believe has ones at a reasonable price. Avoid ones marketed by Scan-Tech. Good luck, and treat those compressed springs with the utmost of care. They are potentially quite hazardous. If you really want to top off all of this work with a nice finish, have your car realigned, especially if you have changed out tie rod ends as well as ball joints and struts.
