Answer 1

System.Diagnostics.EventLog log = 
    new System.Diagnostics.EventLog("YourLogNameHere");
log.ModifyOverflowPolicy(
    System.Diagnostics.OverflowAction.OverwriteAsNeeded, 0);

This should fix your overflow problem. The event log is generally extremely reliable, once it's configured correctly. When using the event log, I used to add a quick emergency backup logger that simply wrote to a text file (this takes about 5 minutes to write). It never got called.
