Will like to book concerts in Prague and Vienna concerts for late September and early October. Any recommendations where to book tickets on both destinations before our arrival dates.
I bought tickets online for a show at the National Theater in Prague at their official website.
Agree that the first place to look is the websites of the concert venues. Like airline tickets, it can be cheaper, at least a little, if the middle-man agency is eliminated.

i have used this company several times though not for a few year, but at least you will get to see what is on when
Always book directly from the the theatre or concert hall's own website. Resellers add a mark-up that can be as high as 100%.
Here are the official websites:
The National Theatre - including Estates' Theatre, State Opera House and National Theatre
