If your TV and Laptop both have the VGA socket on i.e it looks the same at both ends, then any VGA monitor cable will do the job, no need for any extras. Easiest thing is to do if possible is pinch a cable off sometning else to test. These cables are not a lot of money so don't be foolded into buying one of those super premium pro cables, it's really not necessary.
Audio wise you only have the headphone jack out on the laptop, and the tv probably has component in (RCA sockets) thats the norm anyway so you need to get a Phono to 3.5mm Stereo Jack lead of sufficint length.
something like this I'd imagine

Or if you have a Stereo system especially a surround one then you can rig the audio to that which will be even better 🙂
You will need to check the back of the TV or the manual to confirm this. If you took the manual and possibly the laptop into any decent TV store they should be able to sort it out.
