Can i install a 1GB DDR2 stick and a 256MB DDR2 stick together in dual channel mode ?
If i can't, then tell me whether i should go for only a 1GB stick instead of having a 1GB and a 256MB RAM stick together.
Which of the two options above should i take to get the best performance
My computer has 4 RAM slots.
No, to run in dual channel both modules will have to be the same speed and amount.
I definitely would go for the 1GB module if given the choice between the two. If you haven't purchased the module buy one form a major manufacturer like Crucial, if you decide later to purchase another module to run dual channel you will have a better shot at getting a module which will match the specs of you first 1GB module.
