In the sub 18 range everything can be done entirely on passive gear. The rack you have would be fine for most routes up to the low 20’s. Although I also have a double rack for the lines that demand lots of the same size cams you won’t need them and if you do you will be able to borrow them. There are about 20-30 permanents up here at the moment who you will be able to borrow key gear from if you need it.
If you were to expand that rack for this trip and the grades you are climbing I would add a couple more hexes and an extra grey .4 purple .5 green .75 and red 1 and maybe a grey#4 C4 for the grades you will be looking at and above.
A 70m rope will get you of most routes although a 50-60 and walk off’s will work too, I use a 70.
