I got my BC last month and have now done my passport to

my wife joined me in the Uk last year on a dependant Visa and she is now on a Spouse Visa... been in the Uk for about 1.5 years now... just to mention that she entered before the rules changed (from 2 to 5 years for ILR)...
my calculations say that she will be elegible for ILR in 6 month time... as she would have completed 2 years as (now spouse of british Citezen)
two questions: 1) am I correct in my assumtion? 2) can she apply sooner? or apply for BC directly?
Also for ILR: she already taken the Old Life in the Uk test and she has IELTS ok which would still be valid in six month time.... is anything else needed language / life in uk wise?
thank you all
