Oh, you are going to have so much fun!
If you haven't worked with Forgeworld Resin before, make sure you follow the instructions for cleaning well. It is crucial for the primer to stick to the model.
Don't be shy about using saws, sandpaper and files to neaten up parts and avoid that large gates break off taking bits of the model with it.
Do consider which poses you want, look at a lot of pictures for inspiration.
You will most likely need to reinforce joints with pins, for those models you should be ok with 2mm brass rod - or nails.
Superglue is ok, but you may want to use 2 part glue for larger jobs. That takes time to set, but will be a better joint later.
For knight sized models, painting with a brush is a bad idea, an airbrush is the right tool. Airbrushes are more fun with paints that are produced with airbrush in mind, which impacts pigment size and pre thinning.
