Welcome! Trans and diff service is quite simple if you're planning on just a fluid change. It'll get slightly more involved if you're changing the trans filter, but it's a straightforward job. I personally like to pull the diff cover each diff oil change, but it's not required. See this thread for common maintenance.
Hi, In the short time I've had my sprinter I managed to go through every post in the T1N section and what I have done is to creat a Word document that has hyperlinks to all of the various threads that I have found useful. It includes the standard maintainence threads as well as a bunch of...

You can find the service manual for 06 and parts catalogs. You'll also want to have a look in the service scans folder for more specific info on certain things. There's also lots of useful PDF files, guides, retrofit options and such towards the bottom of the main list.

Oil lots of people run is shell rotella T6. It's what I use, but there are plenty of other options. The biggest thing is the MB spec ratings, search for the numerous threads on oil.
For the AC, it's usually never a simple recharge to get it going. There are a few very common issues that make the AC not work. You would need to do some troubleshooting to figure it out. The most common is the control module on the dash has a faulty solder on the compressor control relay. The module can be removed and sent out to
https://www.shop.modulerepairpro.com/ and repaired for about $120. I do not advocate for DIY AC charging unless you are using vacuum pumps and manifold gauges and have a thorough understanding of AC systems. I do always recommend that people have a professional shop service the AC.
(by service I mean recharge) Replacing components and troubleshooting can easily be done DIY.
I would
highly recommend you purchase a
sprinter specific scan tool, this is hands down the most useful tool for any sprinter owner ever period. A generic OBD2 is not very useful here. An Autel AP200 scanner (amazon $70) seems to be the best bang for buck currently. This will help you immediately troubleshoot you're AC issue to see if the compressor is being properly triggered by the relay. Also tells you AC system pressures and such which will tell you if you currently have a charge (but not how much) in the system.
