What needs to be done to access the oil pickup tube? Having the top end worked on and wondering if the tube will be cleaned during that process.

Access to the oil pickup requires removal of the oil pan - not a fun task and not part of a top-end re-work. If the engine has had regular oil changes, it's unlikely the oil screen will be clogged. You can also ask whoever is working on the top end, how much buildup of gunk or sludge they found inside the valve cover and on the valve train. Hopefully they can give you they're educated guestimate of whether you should be concerned about the rest of the engine and the oil pickup in particular. If you're still concerned about a buildup, geezer101's suggestions are very good in that they're effective and easy to perform. They're worth a try before taking on the time and expense of removing the oil pan.
