assistant: Typically a touring bike will be similar to a racing bike with cantilever
brakes (like a MTB) which provide more stopping power for a loaded bike and a
triple chain ring (like a MTB) providing some powerful granny gears.
Remember a tourist is carrying a lot of gear in panniers, so the bike and
load is significantly heavier than a racing bike, which is stripped for
speed.  The tire diameter is usually the same as a racing bike (because it
offers less rolling resistance) but the width is typically somewhat wider
than a racer, although not nearly as wide as a MTB; the touring tire will
also not have the knobby tread of a MTB, which gets awfully old on the road.
The 'cheap and easy way' is to stand over the frame.  On a road bike you
should have about 1" clearance between the top tube and your crotch.  On a
MTB 2" is more like it.  This will probably be the method used if you go into
a bike shop and by an entry level bike.
Some really good coaches can look at you and come very close to a good fit.
The guy who started me out on good bikes could do that.  But not everyone
can.
The best way is to actually measure.  There are formulas for translating
inseam and other measurements into one of the standard frame sizes with
appropriate stem and crank sizes, so that the bike comes close to being
'custom' unless you have really odd measurements.  The common measurements
are made using something called a "Fit Kit."
Yes.  We're switching tire sizes from "English" to metric.  Those sound about
right for a MTB, although I'd think it would be 559mm x 47mm.
Yes.  Typically these are now '700C' with widths ranging from about 20mm for
extreme racing tires to about 35mm for extreme hybrid tires.  I typicall ride
about a 700C/25mm
