keyless entry FOB module

hello all i need some help here i have a 1998 sonoma whit no power windows nor power locks, i want to install a POWER LOCK FOB MODULE but i dunno how can i get the right module for my truck, i have some questions, here they are.

1.- since my noma has no factory power locks, can i use any FOB module to install power locks?????, i found two modules on s10warehouse on ebay, even the door panels and switches

2.-i know i need the wiring harnes for the above, but do i need to have the factory wiring harnes???

3.- any ideas were to get the complete set, i mean power windos and power locks, i like to have the factory installation????

thanks in advance
