I am not an expert, but it is my understanding that IELTS used to be valid for ONE YEAR, but that changed to two years a couple of years back. SO, if you submitted your IELTS in 2008 around the time of your application submission it would be valid. It would only be a problem if you had not yet submitted the results.
Sorry, but I don't know how to answer your other questions.
The ILETS was submitted before 2009 started. Application was rejected because I was missing some information. Would that application still be pending now? Do I need to take ILETS again? Any other option besides the IELTS?
