Yes, Choosing a reliable travel agent is very important for spend two day. I found a website  www.localvibeguide.com/ where you get PAID for writing local guide. You can also get local travel information for visitors of most of the places. One must avoid the tourist traps and discover what the locals do.

Kulamlampur is a great place. there r lots of place for shopping and stuffs.i am sure you'll have a lot of fun there. 

Many many places to eat. KL City Centre is by far the best place to get food. Step into Suria KLCC, a favorite shopping complex for locals and tourists. There's a lot of foreign and Malaysian foods to sample. Vivid Dance club is the most known and fun is always had by all. They have a Hard Rock Cafe too that play a lot of rock and R&B. 

You'll have to squeeze a lot in the two days you are there, but make sure you visit these spots during your stay.
