DSS is totally fine...

I assume you're referring to the annular version. I've had one for a few years now with no issues. I could understand the reluctance to roll dice with a homo-kinetic axle, but the nice thing about annular axles is even if you need to warranty one, there's no need to reopen the diff to change it out. Once that mount is in there, you're good to go.

There are stories out there, and on here, about the bolts backing out in annular axles -as D911 referred to above. Re-torquing before install should solve this issue. Possible they're not coming off the line with proper torque. After a year of running that axle, I noticed a bead of grease on the seam. The bolts had in fact loosened. I torqued them down to spec, and have heard not a peep since (two years later).

You can't use thread lock. Degreasing the threads makes no difference as they're passing through a grease cavity by nature of the design. The lock washers supplied should be fine. If you're concerned, you can easily replace them with lock washers of your choosing.
