In brief, Deepavali is mainly celebrated at home. So once you have settled in Kuala Lumpur and have made some Malaysian friends, you will be invited to their home (which is also known as "open house") to enjoy the festivities with them.
Otherwise Indian temples are your best bet such as Batu Caves or Sri Maha Mariamman Temple in China town.
Most neighbourhoods also have independent firework displays and all shopping malls will display a wonderful, colourful Rangoli/Kolam at their entrances. These beautiful, artistic designs are usually made up of coloured rice. Very intricate and very beautiful, these Rangoli's will make you stop and admire the painstaking detail that goes into them: one rice kernel at a time!
Below is a Rangoli from KL Sentral this year: 2012.

This year there was a Deepavali Carnival hosted at the Bukit Jalil Sport Complex.

Lastly Brickfields and Masjid Jamek are slowly, year on year, beginning to host mini celebrations. This year there were some stalls in Brickfields to mark the celebrations.
