As far as the Anavar, most posters thin 40mg/day for 6-7 weeks is the usual, but usually combined with something else.
not enough clomid to do post cycle. arimidex is good to keep the water bloat down while doing the cyp, but with only that much cyp, you would only have enough for 250mg/wk for 10 weeks.
You could consider doing some Deca for 10 weeks, with ~250mg of cyp week, and you probably wouldn't need the arimidex. You want have a lot of water bloat on that low of a dose. Then followup with the clomid (if you can get enough).
All this off course depends on your goals though.
hope this helps.
