The first question is: how can I get the C compiler to work properly? When I've tried to compile programs, I get 'cannot create temp'
Try checking to see if there is any disk space left on the root RL device.  It may be full -- these were tiny by today's standards -- disk drives.  10 Mb, if I recall correctly.
The other possibility is that the /tmp directory has the wron permission.  It should be read/write to all (drwxrwxrwx).  If not, try running chmod 0777 /tmp as root, then try compiling again.

Also, how can I get the backspace key to erase? I've done stty erase '^H' but I have to actually type <CTRL>+H to erase.

The other thing I want to ask about is: can I compile SIMH on DOS, so it doesn't display any messages except those of the simulated software, and so it ignores ^E?
You can fix the control E problem by running the command
... where char is the charcter you wish to use.  (WRU stands for "where are you" according to the SIMH documentation http://simh.trailing-edge.com/pdf/simh_doc.pdf).
I'm asking because I want v7 on an ancient laptop I've got lying around - a 486 with 24M of core. v7x86 won't work on it, and I don't really fancy putting Slack 3 back on it - if I'm going to go outdated, I might as well go the whole hog and go really outdated.

Though I might consider 2.11BSD, if that'll work on a machine with 24M of core, and if the escapes will display properly, because
The biggest PDP-11 had 4 Mb of memory, so you certainly won't be limited there.  I suspect that if you run nothing else,on the machine you will get fair perfomance on the emulated PDP-11.  2.11 BSD should run.
As far as your other terminal problems, you probably just need an appropriate setting for the TERM environment variable to get vi to work.  Usually TERM=vt100 works, but your mileage may vary.
Real men use ed, though!    I always amaze people by being by being able to use ed.  Of course, that's because I'm very old -- old enough to have actually used V6 on a real PDP-11.  I think I'll take a nap now.
