Basically I have a basement area / workroom. Two regular edison light
bulb slots.
I would like to replace them with three Fluorescent strips like this
http://www.lowes.com/lowes/lkn?action=productDetail&productId=163719-337-SS232UNVEB81&lpage=none
Item #: 163719 Model: SS232UNVEB81
from Lowes.
So my question is How do I get power to the center one?
Just buy X amount of cable, hard wite those babies where the bulb
sockets are now, and just cap it off from where I connect the
fixture's lights to the house power?
Parallel?
Or can't I do that with Fluorescents?

Yep, can be done. Three lights in parallel. Essentially the flourescents
are wired up just like the existing lights. There won't be any need to "cap
it off" at the end of the line, since those power wires will be connected to
the flourescent light. (if "cap it off" means cut the wire & put wire nuts
on it, connecting to nothing)

No, what imeant was, twist two wires, put a cap on it, electrical
tapeon there, and stick it on a junction box if its outside the
fixture. Which might not be needed actually.
I look at the four footersand they put off enough light at work for
the whole area; this room is smaller but doesn't have as many bright
walls.
So I'll start off with two, and if I need more I'll cross that bridge
when I get there... As Ted Kennedy used to say.
I won't do this for a while, hence the otherperson in the other thread
is somewhat overreacting. I want to get all the info before I start
tripping breakers and cutting wires.

Fluorescents wire up the same as any other light.

Just for the record, I have to report that fluorescent fixtures do not
***ALWAYS*** perform the same as incandescents even if they are wired the
same:
I purchased 24 fluorescent strip lights from Home Depot, each containing an
electronic ballast and sockets for 2 fluorescent T-8/T-12 style 32 watt
bulbs. These fixtures use the newest electronic ballasts, are extremely
efficient, make no hum or other noises like magnetic ballasts, and were on
sale for $6.99 per fixture.
When they were all installed as three sets of 8 fixtures, each set on its'
own circuit/switch, I found that an extremely high rate of failures
occurred, arising from what I subsequently learned is called "ballast
fratricide", a process wherein the switching transients from the ballasts
all being simultaneously switched results in spikes which the ballasts are
unable to dissipate without damage.
It turns out that strip lights especially are not filtered adequately,
neither in terms of the emitted spikes which damage other nearby/connected
loads, nor in terms of rejecting fast transient spikes which arise elsewhere
and need to be dissipated.
I spent some time with an oscilloscope and a lot of measurements before
being able to find where the problems were, and have subsequently learned
that others have reported the same type of problem with the newest
electronic ballasts in some commercial installations.
If one takes an in-depth look at the schematic and waveforms produced by the
electronic ballast during the start-up cycle, and also looks at the chipset
spec sheets from the ballast ICs involved, it becomes apparent that huge
switching transients are typical, and that external filtering is up to the
fixture designer who incorporates these ICs into their ballast.
The bottom line is that some fluorescent fixtures cannot be simply wired as
if they are incandescents, since they will destroy their neighbors and
themselves, in my case over only a few days of normal use.
My solution was ultimately to replace all 24 ballasts with another, better
filtered design which, unlike the Home Deport brand, have a lot of spike
filtering as well as a 5 year warranty.
Here is another example of this type of problem:
