If you are planning to visit the castle there are 3 things I think you really need to know:
1- How to get there. There are three main ways. a) You can walk from the old town- it is about 30 minutes from the Charles Bridge, but up a big, steep hill. b) You can go to Malostranská metro station- it is a bit nearer to the castle but still at the bottom of the hill. Near the metro there are some steps that take you up to the castle. c) You can take tram 22- it is a long line that runs across the river and will take you up the castle hill. It is an easy walk to the castle from the Pražský hrad (Prague castle) tram stop. You can even get on this tram outside Malostranská to take you up the hill- and remember that as long as you keep within the time limits of your ticket, the same ticket can be used for different forms of transport.
2- The security lines- There are several ways to get into the main castle complex. Each has a security check. From my amateur observations avoid mornings and weekends if you don't want a long queue. Even if the queue is long it seems to move pretty fast.
3- How you want to approach your visit- There is a lot that you can see for free but a lot you have to pay for too. For free you can walk all around the main areas of the castle complex (including into the first part of the cathedral but not all the way in). You can walk along the beautiful gardens along the ramparts too. There are lots of places to eat and drink within the castle, but if you want to keep costs down I would find somewhere outside the walls- and just by going a few streets away you are less likely to get tourist prices. The castle isn't like any that I have been to before- it is a mix of a castle, a palace, a religious centre and now a political hub. In my view aside from the cathedral there are no 'must see' buildings, it entirely depends on you and what you enjoy.
The other thing to think about when visiting the castle area is what you'd like to do afterwards once you have taken the effort of getting up the hill! Rather than simply walking down again you could choose to walk up the Petrin Hill on one side of the castle or go to the lovely Letna park on the other. Again, don't just follow the crowds- the whole of this part of Prague is stunning.
I have had the pleasure of living near the castle for about a month (basically a few stops further up the 22 Tram line). It is beautiful viewed from any angle and the whole area in and around the castle- for example the Royal Gardens (where I went for a beer festival!) is worth seeing.
Most importantly, when you visit the castle try not to worry too much about what other people think you must see. Just enjoy your own visit and soak up some of the history and stunning views.
