about a few vbseo configuration parameters

I'm not sure what to set for the following set of configuration parameters. Perhaps, you can help me (what did you set? did you succeed with it?)

1.
Replace Non-English Characters in URLs? (now: remove)
My board is german. I think, I should change this, but does it effect search engines in a negative way because of existing content?

2.
"File Not Found" requests handling? (now: show 404)

3.
Add Google Analytics "Tracking External Link Clicks" Code? (now: no)

4.
Replace 'Previous/Next Thread' redirect links? (now: no)

5.
Acronym Expansion UPDATED! (now: no acronyms listed)

6.
Add rel="nofollow" to ALL External URLs (now: no)

7.
Cleanup HTML code? (now: no)

8.
Remove last post for guest visitors (now: no, keep it)


Thanks a lot!

I would like to see you:

• Keep 2 the same.
• Enable 3 only if you desire to use this tracking mechanism in Analytics.
• Enable 4, unless your server does not perform well.
• Add acronyms IF there are any important terms that people commonly use short forms of, where those shorts forms are NOT as popular in the search engines as the full term.
• Keep 6 the same only if you do not discrimimate on links posted in your forum. If you tightly control and monitor linking, it might be better to disable it and allow some relevant links to pass value. You should also check out our conditional signatures plugin.
• Enable option 7.
• Enable option 8.

For the non-English character option, I will await feedback from our Global Partners team.

Thanks a lot.

okay, I'll wait.

But on point 6, I now saw something that prevents me from setting nofollow for external links:
To nofollow or not to nofollow
