yes. Everything below 90°C is fine and the GPUs are usually setup in a
way to protect themselves against overheating.

The card temp (sensors) went from 44 degrees to 53.
Is that still an ok temp?

Defaults to whatever state the VBIOS puts it into.

echo 0a > /sys/kernel/...

Note that you really want to be on kernel 4.10 or so in order for this
to work well. (Working poorly = failure to reclock, or system hang
afterwards.)

$ sudo cat /sys/kernel/debug/dri/0/pstate
07: core 324 MHz memory 648 MHz
0a: core 540 MHz memory 1620 MHz
0f: core 1058 MHz memory 5000 MHz
AC: core 324 MHz memory 648 MHz

Wow, it defaults to the lowest.
Is there a way to change it?

cat /sys/kernel/debug/dri/0/pstate

AC (or DC) line shows the current state.
