Haha - I guess when I Google the parts, there are several types of 910ohm resistors (e.g., 1/2 watt, 1/4 watt, metal film? etc. etc.)

I have no idea which ones to order. I can take a stab and create a list, but can someone verify if I have the right parts in my cart?

In this case I would order 1/2-watt metal film or metal oxide resistors. Just about any 1/2-watt metal films or metal oxides will do in your case because they are for a basic measuring instrument and will not be in a signal path. The 27-ohm resistors are already noted as 10-watt. The military designation would be RN-70 for 1/2-watt resistors.

We all have to start somewhere. I remember getting my first box of stuff from Digikey and looking at the little plastic bags and thinking 'these must be the capacitor thingies'.

Attached is the list of stuff as I would order them from mouser.com I will leave the box to you.

We all have our favourites and I happen to like Mouser, but I do buy parts from elsewhere as well. Digikey and the other suppliers are fine. I hope this helps and that I have not made too many errors.

Ray,

Thank you for posting the list. I ordered the parts included in your PDF. Goodluck to me :-)

Some of us even go all the way back to putting together Heathkits and Dynaco kits. SWTP (Southwest Technical Products) wasn't bad either.
