You'll need slings and biners too. Eight to twelve 24" sewn spectra slings is a good start. Try to keep them the same color so you can quickly identify single vs. doubles. I use two to four doubles to supplement this (especially for wandery alpine routes.)
People will rack differently, but I tend to rack my singles in trippled quickdraw fashion with two biners each. If so, two dozen lightweight wire gate biners is a good start. Again, I'll pick a specific style or color to quickly identify which go with my slings.
Also a general buying tip, you'll get discounts buying in quantity, so it's more expensive to buy things one off the way you are. Save your pennies in a piggy bank and make a larger purchase all at once.
