Updating from etahen

Hi folks, haven't been keeping up with developments for a while and looking for some advice on updating things. So my current setup is 10.01 ytjb and I just run in the ytjb autoloader folder on the hardrive with only the etahen and backpork .elf files. I use an external nvme drive.

This has all been working great but I noticed with the new games exfat format and apr emulation they arent working for me. I see posts about shodowmount (plus), kstuff (lite?), etc. So my questions

1. What should my autoload.txt look like these days?

2. Bit nervous to try out a whole new setup like this, can I run it off USB stick first to test it out before? Then edit in FTP on the hard drive?

3. I'm getting a psvr2 soon and was reading that etahen has something that spoofs it's version number so it will work, does shodowmount also do this or some other payload or app?

4. Currently I can FTP into the ps5 from my PC (I have DNS set to 127.0.0.1) should I be using a DNS blocking payload instead? Does shodowmount do an FTP server like etahen or is that something else?

5. Onionhen? What is this could I use it instead?

Thanks! Sorry for many questions
