I have been reading for hours on line and then I found this site :-) I
need help with terminology, wire guages needed and a bit of how to.
This is long so only the brave please continue.

The house was built in 1900 and half of it was rewired before I bought
it. I am putting in a a second kitchen so my divorced daughter can have
her own space and we don't tear each others hair out. The back part
where I want to put in the kitchen has the old wiring with ceramic
tubes in the joists. They make pretty good whistles if you blow just
right :-)

The new power supply to the house is about 10-12 feet away from the new
kitchen room and it has a master shut off for the house and the wiring
is covered in conduit. Is this the Panel or the sub panel?

I need to install a new box with breakers for this kitchen inside the
house. How do I add up the Amps needed in order to buy the breaker?
There will be an oven, separate stove top, microwave, dishwasher,
garbage disposal, 2 ceiling fans w/lights with ceramic heaters, 2
indoor lights, 2 outdoor lights, fridge ( is that 110?), airvent
extraction fan, thermostat for the underfloor heating and 9 x 110 power
outlets for kitchen appliances a TV and plug in electric heaters (there
is now forced air in the back of the house) a washer and a dryer. I
think the amps are different for all of these and does it depend on the
watt consumption?

Should I run all of the wiring in conduit or just the 220 wiring? Only
the stove top, oven and dryer are 220 right?
What guage wire should I run for the lighting, outlets, 220, is the
fridge line a different guage. I should use outdoor wiring for the
outside light ? What guage?

I got a quote for $2500 and that's probably very good but I can't
afford it so I was planning on installing all the wiring up to the new
breaker panel and then asking an electrician to hook it up to the
mains. That sounds scary to me

For the plumbing I there was a old sink back there and I pulled up the
floor and it's got galvanized pipe and cast iron drains going into the
main drain. I think this was the original kitchen part of the house.
Is there an adapter that will let me connect black plastic drain into
the cast iron drain? Is there an adapter that will let me connect to
the galvanized supply lines for hot and cold.? What kind of pipe
should I use for these new lines? Should I run a separate drain from
each of the sink and the dishwasher to the main drain or can they go in
the same drain from the wall over to the main drain? Is there any kind
of a valve I can put in that will help with water pressure so when I
have the dishwasher on I can still use the sink? Do I need a separate
ventless thing for each of the sink and the dishwasher or can they
share one? Do I need any drain valves to prevent "backwash"? I was
planning on adding a garden tap off the cold water supply into the
kitchen is there anything special you have to do to make sure it
doesn't act as a cold conductor and freeze all the pipes? The walls
are wood siding like a shed so it gets cold in there. Can I take the
outside tap directly off the sink line near the wall or should I use a
three way supply to each of these 1. sink, 2. dishwasher, 3. outside
tap from the existing supply line? Are there any questions I forgot to
ask?

Lots of questions and yes I know I am certifiable. Please respond.

The site that buffalobill referred you to is great, but I agree with MDT.
You are in over your head. If you can't afford to hire it done turn key;
ask if you can hire an electrician as a consultant. Let him tell you what
to do, and you do the work. The truth is it will be more trouble to the
electrician than your fee will be worth, but if you ask enough of them,
you'll find one that is willing.
