Don't do it in that order - either one, or the other. The weedkiller must be sprayed, then given time to work. It is absorbed by the leaves, and is taken down to the roots, to kill the lot. Spraying, then pulling them out, is just a complete waste of weedkiller.
Make sure you fill the gaps between the blocks after cleaning. Most block paving jobs use free draining material such as 1-4mm Joint Aggregate . Kiln Dried Sand is rarely used now. Using Joint Aggregate over Kiln Dried Sand seems to be better in reducing weed establishment IMHO.
