That is not a bad selection. Powers are 59x, 83x and 125x and using a barlow you get 118x, 166x and 250x. As the 17mm barlowed would give similar power to the 8mm unbarlowed, a 2" barlow id probably unnecessary.
I am a believer in have a low power EP that gives a nice 4mm exit pupil for at least one EP in a collection. The 17mm will give you 3.4mm which is pretty close.
Also I note you have gone the 12mm which gives better eye relief than the popular 13mm T6.
Overall a good choice.
