Thanks for taking interest in my latest little project 
Some basics:
You need to solder! so get some tools so you can learn as you go along
Ok the first thing you need to know is that a white led needs 3v to light up, red ones are I think 2.4v
so the first thing you need to work out is how to power them. Its possible to use a 2xAA or 2xAAA battery box or a 3v lithium button cell with a switch and a resistor wired in if required for outside (scenery etc).
In a loco space can be very limited for batteries, as I found out with arry n bert and a long way back with light up Paxton. Some talented members here discovered a little device on ebay called a step up voltage converter that can turn 1.5v from a single battery into 3v to power an LED and even both the loco and an LED at the same time! This is my preferred choice when I want to do light ups now as its extremely effective and throws out allot of light compared to the old method I was using which was a grain of rice bulb.
There are some great wiring diagrams and the end results in the electrical engineering thread Here
