PIC to Ligicator - Serious noob here

Hey all, ive just received quite a few componants tho i dont know what most of them do, i am learning about the datasheets of each peice that i have tho, i just need to know a few things and any support i can get to get this thing rolling...

Processors i have:

uM-FPU coprocessor (V2) // PICAXE-08M microcontroller // PICAXE-18X microcontroller //PICAXE 28X2 microcontroller

 

my goal is to interface with the program called "logicator" so i can see the code and learn from it and eventually code my own output

i have:

Burning the Arduino Bootloader with your Arduino as the ISP programmer

I noticed that the Arduino 0018 software included the option of using an existing Arduino as a programmer for burning the bootloader onto blank ATmega chips.Below is my Arduino Nano configured as per the instructions.

This sounds like a great idea but I am having trouble getting it to work in practise. Usually I get this error:

Does anyone speak Latin around here?

I am soon to get another tattoo and I want it in Latin. This will be on the back of my neck, just above a tee-shirt and just below a proper button-up shirt with a collar. Obviously, I don't want this to happen.

I have had this particular phrase with me for a while now and I stuck it into a simple online translator.

LMR-o-Scope

LMR on an oscilloscope.

I used Chris Meighan's ScopeShapes program to drive my oscilloscope from my PC sound card.

The program was loaded with a DXF file created by Armin Müller's eleFont program.

List of good online shops for bot parts

I was wondering where online most of you go to shop for parts? Can we construct a master list of important websites here?

This list is from the URLs I've gathered from the various tutorials:

Soldering

A while ago i was looking at some websites which helped beginners build robots. I came across two prominent sites and checked their Start here(first) robots. I found that LMR had an easier to build start here robot which i could have fun building. But there was one major problem, i could not solder. The next day i got some parts for my start here robot from Techsupplies UK and the same day, i went to a local electronics store and bought a cheap 4$ solder iron and 45gram solder with a 1$ de-soldering manual vacuum pump and a stripbard and some male header pins.

Wireless camera plus lcd screen

Ever since I have seen the land warrior system ( http://dsc.discovery.com/videos/futureweapons-land-warrior.html ) I have been thrilled and wondered how hard it would be to make a simple version for airsoft or paintball.

I just thought I would put a camera on an airsoft gun, helmet, or  something and then it would relay it to a screen preferably on a 2.5 inch screen so it is on the eye and portable. 

I would like to know if the wireless camera could keep up with the movement of someone walking for a half way decent image.

My equipment would be -
