I take temps after the cooler, before entry into the block. I bought a used cooler, so I plumbed my system with the filter as the last component before oil goes into the block. The CV products oil filter mount I used has a provision for a temp sender.
I wouldn't plumb an external oil cooler/filter set up with anything less than -12 lines. You don't want to induce any more pressure drop through the system than necessary. Make sure you don't use the socketless fittings, they have always leaked for me.
You may want to consider using a filter/mount that uses a 1 1/2 - 12 thread vs the typical 3/4 - 16 thread. You can get filters sized for diesel trucks (at the regular parts stores) that have WAY more filter area than a normal size filter. More area = less pressure drop.
