My roof right now are concrete roof tiles. After hurricane Wilma about
20 tiles broke, cracked and missing. The rest seem to be in good
shape. However, many of them have been "shifted" from their original
position. They were originally all mortared in (a thick blob of mortar
between the tile and the tar paper underneath).
Location is Miami, Florida. We don't have snow and freeze/thaw. I
have seen posts that suggested the proper method to attach concrete
roof tiles is to nail them. I also heard that screwing them is the
best. Then I called two local contractors who then said to me "are you
crazy? That's what they did out in Weston, nailed every tile to the
roof and now nothing but leaks, you can't believe what they are going
through". One other contractor told me I was "nuts" to try to reattach
all my tiles back on, that it will be more expensive (laborwise) than
replacing new tiles on my entire roof. He suggested that he just
inject RG45 (?) to a couple of spots and the tiles should stay on their
own by their weight and their interlocking edges. I said what if the
next hurricane comes? He said well this is a one in a 50 year thing so
that's unlikely...
So I am confused whether I should spot fix only what's broken, reattach
all loose tiles, or replace my roof. Is the nailing method the proper
method but their bad experience is due to poor workmanship and inproper
installation? or is it not desirable in south florida?

Concrete tiles on my home were nailed. Tops,valleys/cuts, ends were
cemented.
I do know of some tiles are installed differently
You will need to find out what you have and then replace in like kind.
Sorry the only RG45 I know of is a coaxial cable, reasonable sure that is
not the case here.
Weather service says the storm outlook for next year could be as bad. Of
course I am speaking of weather forecasting, which I equate to "practicing
medicine"

Every 50-100 yr old house ive seen was nailed, go to Europe, or look at
photos of houses much older, nails there too. You figure it out, its
simple.

Well, the method that was used before came apart, so THAT'S obviously
out...

I understand that the codes in FL now require nailing, although many
roofers are prone to cheat with mud on the 5 courses closest to the
eave...
You should be able to repair the roof but will need to buy extra
material to allow for damage you will do while working.
I bet you can get some good info from the following web site:
