Has anyone replaced their shocks and struts yet on their 05 + mustang? If so, what mileage did you do it at and how difficult is it to do the front struts?
Most manufacturers recommend shock/strut replacement at 50,000 miles, depending on your driving style. However, I am a big believer in not fixing things that aren't broken. If your shocks and struts aren't rusted through, leaking, or letting you shake all over the road, you don't really have to replace them. It's a good idea to keep an eye on them and check them every other oil change or so, though.
If this is your first project--or one of your first--it's a good idea to have a shop do the install. For one thing, it's pretty difficult to do the shocks if you don't have a lift, air tools, and a strut spring compressor. For another, changing out the struts requires an alignment, which in turn requires a shop. A good shop usually charges about an hour per side, depending on their labor rates. Your best bet is to call your local shops and see which one has a mechanic that's familiar with Mustangs or Ford vehicles and ask what they'd charge you for labor and an alignment. You'll also want to see whether or not they'll let you supply the parts, or if they insist on providing their own parts (this isn't usually an issue, but some shops are picky about what parts they'll install).
I changed my shocks & struts out at 65.500 miles. I installed Koni STR.T. Now I have my own lift, but it really wasn't too hard of a job. You need to rent or borrow a spring compressor to do the fronts. Happy with the results.
I did the install myself and really it sounds more intimidating than it is. If you have a decent jack and tools you will be fine. You can rent a spring compressor from Autozone or checkers for cheap and if you do the install yourself, you will save yourself about 300-400 bucks in labor. Start here:
