orwg comes in very small bottles and if you are in a cold climate you should wait until it warms up it gets all messed up in cold weather.
you dont need lace release, it is just expensive alcohol IMO use 99% alcohol and you are fine, no need for the 91.

i suggest you order autoglym, its way better than other solvents for cleaning a lace system.

maybe get some back2natural (google it) i guess the best way to describe it is its a color conditioner..its good to battle oxidation, gets unwanted tones etc. sucks when a system arrives and it has unwanted tones that your hair doesnt have. it doesnt always happen, but better safe than sorry.

i dont recall is you are going to someone for a cut in or doing your own. if you are doing your own i suggest blending shears and a razor comb. both of which should be handled with caution.
