Any cautions about this setup?

I don't have power anything in my 4 door car.  But am hoping to go to keyless entry and add an alarm.  I don't know if it'd be better to do just the front 2 doors, or wire the driver's side and the other 3 seperately (rear and passenger all on same button).  I won't add remote start cause its a manual.  Here's what I plan on buying.

Alarm w/ keyless entry option.  2 remotes.  Aux. trunk output, and 2 sep. lock/unlock buttons on remote.

2 or 4 2 wire actuators

What am I missing?  Are any extra relays needed?  I'll unlock the doors inside using the old mechanical attachment instead of a button. If I wanted to add door poppers I'd need to just have 2 extra channels on the remote and 2 solenoids correct?  Thanks a ton for the help.

I will need extra channels for a door popper kit, cause they are seperate devices from the actuators.
