Need advice, Remote started, power windows and keyless

Hi, my 03 ce auto, hos manul windaows and doors.

but I bought that KARR alarm for $400 (stupid me) and it also opens the driver door.

Now I want to get keyless entry (to all doors) power windows and a remote starter.

here is what I found, is it good?

4 Door Power Lock Kit (Universal) $45

anyway I can get those two on one remote?
and posbly hook up my alarm system to their remote? (cuz KARR has 20feet max range)
