Definately worth it. Get a variable ratio pump. Set it to 29:100 and
test pump some resin through. Check to see if you are getting a 1:4
ratio by weight and if not then adjust the pump until you do. You can
mix the hardeners if you wish to get the right setting ratio. I use a
50/50 mix which is right for my winter climate though I will have to
use more slow hardener for large layups as summer arrives.

Here is the list...
3M mask with organics filter and dust pre filter.
Rubber gloves, the washing up kind, not surgical.
eye mask with facial seal.
Tyvek coveralls
A good ventilation system for the workroom.
Dispose of all rubbish from the workroom after each layup and if
possible treat mixing cups, stirrers etc as disposible items.
