Converting double crank to triple crank: 1986 Raleigh Technium

Triple sounds ideal. My research so far leaves me with the following questions:

1) Will I absolutely have to get a new, longer spindle? If so, how likely am I to find one that will work with my 1986 Raleigh Technium bottom bracket?
2) Will my existing down-tube mounted, friction style shifter work with a triple? What is the max tooth difference that this type of derailleur can handle?
3) In an article on converting doubles to triples, http://www.stanford.edu/~dru/tripleize.html, a device called a tripleizer is mentioned, but all leads on tripleizer have run cold. Any exp on these out there?

It is starting to sound like much $$$ and time. I was hoping to spend around $200-$300, anymore starts to sound like a down payment on a new machine.

I would like to know if I can replace my 6 sprocket free wheel with a 7 sprocket free wheel with a 30, 32 or 34 tooth granny sprocket. Would be a lot cheaper than upgrading the front..

Thanks
