Which policy should I invest in?

I am 27, and planing to invest Rs. 25K – 30 K in policy’s annually . Till now I am having LIC’s ULIP policy (for 10K), which is running into its third year. But planning to stop it after few years. Apart from it, I dont have even a basic medical policy. Neither do I have any basic idea about tons of policy’s available in market !!

So dear friends, guide me in following matters:

My basic requirements are: life cover, medi claim (which includes accident cover also i suppose), post retirement benefits (planning to retire at 55+), and flexibility to surrender policy with minimal damage (will keep policy of atleast 13 years).

Friends my question is, whether to buy different policy’s to suit my requirement ( i suppose some of my requirements can be clubbed together) , or get some policy with all that in it ( i m not sure if there is 1 with all that) ??

Also, by seeing the resent up and downs in market i m not sure is it best to invest in policy which has 100% proportion in market .

Please HELP
