BCredliner nailed it on what is pressing now, what needs attention, and what are the steps to determine what is actually leaking and how much. At that mileage the list is short so you are OK with a few DIY projects. Search the forum and the projects will not seem so overwhelming. The inspection and next steps outlined for you on the outer axle boot is spot on. I did mine in 2 hrs with no issues what so ever all due to the efforts and knowledge on this form. My investment was $40 for an OE boot and a few tools to lock down the boot clamp. Search for "CV Boot replaced in 20 minutes" and you will find all you need. Some of us took longer to do the job as we are "Challenged". Or maybe we wanted a cleaner end result.....
Add the normal preventive maintenance items that should be done as a process to prevent future issues. Examples: All fluids front and rear diff, brake fluid, antifreeze (BMW only fluid), plugs, valve cover seals, filters air and HVAC. There is a whole range of topics that can sort this area out for you. Just use the search tool.
There is a lot of DIY in the "How To" sections on the top of this page that can make your life easier. Your 3.0L is the easiest one to maintain so enjoy.
