kafanı karıstırma ! 

Better  work´´-up´´  on that hang around here 

Bu akşam banyo yapacağım ve saçlarım yıkacağım.

Bu akşam banyo yapıp saçlarım yıkacağım.

Here these  2 actions how happen ? One after other ? Or the same time ?

For me is not confusing at all this -up ending. Go to Teach Yourself Turkish by A. and David Pollard at chapter 12 . There is very nice explained.

 Sorry to say Turkaturk but -ip doesnt mean ´ then´ nor ´´after´´

Here is from Teach Yourself Turkish:

   Ïn English instead of saying ´´Tonight Im going to have a bath and im going to wash my hair´´ you can say ´´ Tonight im going to have a bath and wash my hair´´. The second ´´ im going´´ is not necessary so we miss it out without losing the meaning.

   In Turkish you can do things similar but here where you miss a  bit out you insert a signal to let people know you´re skipping something: - ip ending.
