The Toytec lift is just a repackaging of stuff made by other people
The ball joint spacers are made by SDORI
http://sdori.com/pricing.htm
The coils are made by OME
There are better individual prices to be had in other places
The spacers are $119 direct from SDORI or
$99 from 4crawler

The coils are available from Wheelers for $157

That said the doubling of shipping and the sometimes PITA of shipping to Canada could make the package deal from Toytec your best bet. You'll just have to check it out. The BJ spacers have a good track record that you can check out if desired on Yotatech (also what is involved with install) OME products speak for themselves.
Also, here is a list of the spring rates for OME replacement coils.

Keep in mind the OME coils all lift the same amount and are only designed to carry heavier loads. A heavier spring rate will not result in more lift, just a stiffer ride. Your best bet is to evaluate how much weight you think you will be carrying (at all times) and get the appropriate spring.
My opinion is the same on the t bars. They don't actually lift anything. If you are putting on a heavy aftermarket bumper and winch, then the heavier spring rate of aftermarket t bars make sense. Otherwise, t bar lift is obtained by cranking them up tighter. Starting with a stiffer spring just makes cranking that much more harsh.
Also, I'm not sure why Toytec advertises 2 inches of lift. SDORI found that 1.5 inches was the largest safe size of spacer that could be utilized. The conventional wisdom is that one can:
Place the spacers and leave the t bar at stock setting and realize 1.5 inches of lift.
Place the spacers and lower the t bars to something between stock and lifted and realize a compromise of lift and slightly softer suspension.
Place the spacers and crank the t bars to realize more lift with a slightly stiffer suspension.
IIRC you can crank the t bars up to 2 inches of front lift with no spacers but the resulting ride kinda sucks depending on who you ask. With the spacers you can get the 2 inches with only a slight crank of the t bar. Clear as mud?
