Well, at least here is the solution to Event nr. 2:
Download DBrepair from this site and put Dbrepair.exe in x:\program files\landesk\managementsuite\Dbrepair.exe
Stop the LANDesk Inventory Server service
Run x:\program files\landesk\managementsuite\Dbrepair.exe
Clean all except Custom Data
Run x:\program files\landesk\managementsuite\CoreDButil.exe with option BuildComponents
of course, replace X: with your appropriate drive letter...
For Event ID 1.
See the following document.
