[Beau Baker] “But there is only so much I can do with limited upgrade ability on my 32bit.”
The topics I posted about (changing RAM preview preferences, proxies, regions of interest, pre-rendering) are all about getting more preview performance with less hardware. Taking an hour or two to get to know them now will really help to streamline your production work.
If you’re running a 32-bit operating system, you will be somewhat RAM-constrained. I’d suggest keeping multi-processing off in order to avoid RAM problems.
[Beau Baker] “I’m sure Adobe has way of knowing how much each effect/plugin uses”
I think it’s a little more complicated than that; the processor and memory usage of different effects will vary depending on your source footage and effect settings. Experience is a good teacher here; you’ll find that blurs, glows, time-remapping with pixel motion, warps, and big particle systems are generally render hogs — but they’re also all necessary and irreplaceable. Knowing when you’re using a render-intensive effect, and working around it with the tools above, will help you speed up your workflow without having to avoid specific, useful tools.
