Yes, a sampler quilt would be good... except if you have some blocks that two together equals one (i.e., 2 8" (finished) blocks = 1 16" (finished) block), you won't need a sampler.
Graph paper works well for drafting this out.
Since you have some many, i would pile up all the same sizes together, and really assess what you have... and then grab the graph paper.
You might would want to group same sizes in one corner... then the next size in another corner... and so on... and only sash around the "grouping", rather than around each block.
Also, here's an older thread from here on the QB, that might give you some ideas as well...
