Where are you in the project, just getting started, or ready for final renders? Reducing your texture size is easy. You never want to render larger than any of your textures are. In other words, if you are only rendering an 800x600pixel image, you wo'nt need to use any textures larger than that! The bucket size makes a differance in how respnsive poser is during rendering. A large bucket causes Poser to take a long time to cancel, and does'nt always complete. A small bucket takes longer to render, but keeps poser responsive, and paying attention to what it is doing. Your Video card nver has anything to do with rendering speed or size. Your CPU handles speed. And your RAM handles size. All you video card does is help you remember things you've already rendered, when you're working on a scene, so you don't need to re-render. The manual says texture filtering should be experimented with, both on and off. It looks kinda important, say you had a ground plane tiled with black and white checks, so it almost looks like it is going to infinity. In the distance the tiles won't look even without texture filtering.
