You can use the EZ-link card for Bus, MRT and even some of the SMRT taxi. It is cheaper to travel using the EZ-link card compared to using cash or one-off reload card.
You do not really need the Bus Travelling Guide because on every bus stop there actually has a notice board that shows all the routes for the bus which passes by this bus stop. So you can know where you are going. Rule of thumb is that if you do not sure, just travel back to a MRT station and uses the MRT to commute to a place that you are familiar, because the route of the SMRT is published everywhere.
The Bus Travelling Guide book is helpful only when your route in the bus is very long, you might miss the bus stop if you are not familiar. The bus conductor shall not annouced the bus stop name like the SMRT announcing the station name along the way. So you might loss count the number of stop the bus passes by (no stop if no passenger).

I can says that the public commute system in Singapore is much more advance and comfortable as compared to Malaysia. The waiting time between each train is minimum in Singapore, no misses as Malaysia's KTM. The bus transport in Malaysia is no where near Singapore (although Singapore's also has its own flaws). Not enough numbers and limited route. Hence, in Malaysia, it is still very difficult to travel around without car. In Singapore, we able to reach our required destination by public transport.
Anyhow, I still miss driving around in Malaysia =p
