Hello,
If you haven't already found it, check out the tutorial at
http://tangentsoft.net/palmfaq/articles/tutorial/index.html - read it all
though, including the debugging section, as there are some "bugs" in the code
in the earlier section that are "fixed" in the debugging portion of the
tutorial.

Try something like this (from memory, so I hope it's right - somebody'll
correct me if it's not I'm sure ;-):
Char * myCopy;
handle = DmGetRecord(databaseRef, index);
Char *p = (Char *) MemHandleLock(handle);
myCopy = MemPtrNew (StrLen (p) + 1); // null terminated
StrCopy (myCopy, p);
MemPtrUnlock(p);
Could do with some error checking of course, but it shows you the basic
strategy. Remember to free the copy when you're done with it (or when the
application terminates) using MemPtrFree().

Sorry, don't have any info for you on this one... never done anything with
floating point numbers.
HTH,
