ILR as Dependent of Tire 1(G)-Question on English Langauge

[Tire1Questions]

Hello there,
I have a question:
I am a dependent of Tire 1(G) and going to ILR in August 2014. I have passed Life in UK Test. My degree was taught in English but I do not have any proof to prove that.
Do I have to sit in English Lanugage Test. If yes, which one it is and where can I get it from. ( I know I may sound stupid, but I found a few threads on internet but none was same as my situation).

I did sit in IELETS way back in 2009 and had scored 7 band. But I think, the certificate is valid only for 2 years. (I do not think, thats any good-but I though its worth mentioning).

Another question (just out of curiosity: The life in UK test was in English-and i remeber I read it somewhere, if you pass the life in UK test in english you do not need to pass a sapertate English Language Test -becasue the level of english used in LIfe in UK already confirms that you have the basic English Langauge skills (Please correct me if I am wrong)
