It runs fine in all other gears, but if you put it in 5th it jumps straight out. If you try to hold the gear lever into 5th you can feel the gears trying to kick it out.
What should I look at?
The second issue I think I know, but would ask if anyone has any other ideas. When the engine's been running for long enough to get hot it starts a 'clicking' noise that speeds up or slows down with engine RPM, and the oil pressure light goes on and off. I suspect clogged oil drain-down ways trapping the oil at the top of the engine. Any "I agree" or "No, check XXX instead" guesses?

I've been told that when a transmission keeps kicking itself out of gear like that the problem is usually synchronizers, but I can't say that for sure. Your trans is a toploader, so it's definitely an internal problem since there's no linkage to adjust.
As to the ticking, I'd be shocked if it's what you're thinking. When the oil is hot it's thinner. If the oil passageways for drainoff were stopped up, you'd experience the problem when the oil was thicker, not thinner. Sounds like you have oil pressure problems. It may be the pump itself, but it's just as likely to be a worn engine. Worn bearings would explain the low pressure and the noise.
