One or two bites does not warrant compensation, but a severe attack does. A photo of your bitten torso could be useful to show it was not a minor incident. Unfortunately the odd person may look to scam hotels over one or two bites so some proof if needed later is useful to show hotel you really were unlucky.

It would not be unreasonable to ask for points to cover the whole stay so 5nights times xx,000 points/night. Whilst hotel may prefer to offer 5 free nights instead, that ties you to that hotel, which unless you use regularly is not great. I would not expect hotel to pay for the transport costs to/from hotel for your original stay.

Consequential compensation is very tricky (Doctors visit, ointments, fumigating your house). It would depend how badly you were 'bitten' but if that bad, you would likely have raised with hotel during your 5night stay. Like any insurance claims one has a duty of care to keep costs to a minimum. However you seem to be stating a reasonable preference just needing to be comped the number of stayed nights with points needed for that category of hotel.
It is hard to blame an hotel for such incidents, as it could be previous occupant who infected the bed not an ongoing infestation.

Note- Ask hotel for their offer first (don't set the high mark initially yourself)
Since it is impossible to increase your request once offering a lower compensation request, your first step, as it seems hotel manager(ess) is not being negative, is to ask hotel what they wish to offer you. Like you hotel can not offer less once first offer is made so they may well be prepared to go higher later. Really depends if first hotel offer is reasonable or down right insulting/cheap or somewhere in the mid-range

Then you take it from there, if acceptable you can say yes, if not you will need to state what you feel is reasonable and want. Points for five nights seems a good starting point to aim for.
