Default Metal or plastic water pump?

While I take headers off and get them ceramic coating new plugs -coil packs, I figured I should replace water pump - any help appreciated

You want a plastic composite impeller. A OE Porsche pump in a Porsche box. Smart to change before failure.

I would suggest replacing the thermostat as well and take a look at the belt, might need replacing depending on wear.

how often should the water pump be replaced? My car has 110K and I have no record of it being changed...

People like Flat 6 and L&N suggest every 4 years.

Depending on your budget and priorities, consider also :
Low temp T-stat
idler pulley bearings
Serp Belt
Check p/s reservoir for leakage at the neck.
If the coil packs are not cracked/no misfire codes, why change them?
Plug tubes and seals ?
Be careful with header bolts ! Maybe best to leave them alone if they stubborn. Snaping header bolts is a problem best avoided.

I have snapped one bolt on header - all others came out after I ran the engine- I have it drilled out 90 % - can you tell me which parts to order ? All spark tubes look good really don't want to pull those / should I ? -

You are welcome.
The best single,easy source to look for parts is probably Pelican.
Speaking of priorities and budget:
everything stops until you deal with the broken header bolt.Timsert?
There are kits to replace the bolts with s/s studs.A far better solution imho. You can find generic kits on EBay cheaply but you must do all the measurements yourself to get the correct kit.

Lo temp is 160. OE is 187. You can change just the thermostat.

How the eff do you get the water pump out if it only back off with impeller still partially in block?
Also with the finess of a ninja got the remnants of header bolt out and tapped with 8x125 bolt screws in ( slight slop) at beginning better towards bottom

Most sites only have 180 - where do I find a 160
