Check where do they point (e.g in akonadiconsole) and delete the one that is 
wrong.

I assume this is the Favorite Folders. Configure KMail-Appearance-Layout.

Yeah, this is bad indeed.

This is nepomuk related, unfortunately out of my knowledge area.

Again, nepomuk query related.

I'm not sure what you mean here. When you click on a folder, akonadi indeed 
might check for changes in the folder (depends on the folder settings, see 
Folder Properties->Retrieval). If sync when selecting is enabled, this is 
what it should do.

In a nutshell:
- akonadi server caches the mails/addresses/etc. in a mysql database. It 
also stores some metadata for them, like size, modification time, 
read/answered/junk status
- there are akonadi agents/resources that populate the database. They are 
the interface between your data and the akonadi server. Eg. there is an 
agent for vcards, one for maildir folders, one for imap accounts, etc.
- nepomuk can store any other metadata. You can "tag" existing 
files/mails/whatever. It also holds an index in a (virtuoso) database 
towards the data for searching. In case of akonadi this data is 
addressbooks, email body, email headers, etc.
- the nepomuk database is filled up with feeders. In KDE 4.7.x there were 
several akonadi nepomuk feeders for different data types, in 4.8.x there is 
only one for all. This feeder gets the data from the akonadi database, 
indexes it and stores the result in the nepomuk db. 
- soprano is not involved here, it indexes the file system (or is this what 
strigi does? I'm also confused. Anyway, I think it is out of the equation.)
- KMail is a client. It queries through an API the akonadi server for data 
and displays it. So KMail does not deal with the accounts itself, it deals 
with Akonadi. Theoretically KMail doesn't care how the content got into the 
database. KMail can also use Nepomuk directly to get information, perform 
searches (eg. autocompletion for addressbook, full text search in email 
bodies).

Somebody else might know...

git checkout KDE/4.8 (to switch to the 4.8 branch, check git branch -a the 
branch names to get it right. the /remote part is not needed).
configure
build

You need to do for at least kdepimlibs, kdepim-runtime and kdepim. Now I 
don't know, but if any of those depends on a newer kdelibs, you need to 
upgrade kdelibs as well...
