Default Installing boiler thermostat question

Received my new thermostat today and planning on fitting it this evening.

Couple of quick questions...

Firstly, the old thermostat had marked on it 16A 250V~ and T107oC. I assume
that means that it can switch 16A at 250V AC and switches at 107oC. The new
one (the part suggested by Baxi Spares and KeepTheHeatOn.com) has lots of
figures on it (with what appear to be first 3 chars of part number) but the
one for this part says 2(2)A 250V~ 90oC. Can I assume that this switches 2A
@ 250V AC and switches at 90oC? Seeing as Baxi said this was the part, I'm
tending to believe them that 2A switching is okay - and I guess that it just
means that the water reaches 90oC rather than 107oC now? Does this sound
okay?

Secondly, I drilled out the old siezed probe and the hole is now nice and
clear. I used an 8mm drill and it fitted fine. 7mm was too small and 8mm
was tight, but not too tight. This new probe is just under 8mm in
diameter - so it should fit. My only question is whether I just insert it
or whether I need to put anything like heat transfer stuff. From memory,
when a similar probe was removed from a similar Baxi boiler it was dry
without anything on it - so I'm assuming that's right - but I just wanted to
make sure!

Thanks again.
