I am sure you will be OK. WLP-002 definitely clumps when you make a starter. When I first started using the yeast, I was alarmed that something was wrong but soon realized that it was normal for that strain. I have never had any fermentation problems with this yeast.
Regarding residual yeast in the beer, I would think that there will still be plenty in suspension to bottle condition the beer. My reasoning for that is that I use this yeast for my ESB. I cold crash and force carbonate the beer in the keg. My first glass or two out of the keg is cloudy from the residual yeast that fell out when the beer was crashed which says that there were still some yeasties floating around in the beer when I kegged it.
