As for the OS, I would recommend OS 7.6 or 8.1. While 8.5 will run, I find it really slow (personal preference.)
Actually, as long as you have enough memory, you don't want to run either 7.6 or 8.1 on a 5300.
Both 7.6 and 8.1 are full of 68k code that has to be emulated on a 5300 that 8.5 and 8.6 would run natively. The 603e (specially at 100 MHz) is one of the slowest systems when forced to emulate 68k.
So unless you have 16 MB of RAM or less, 7.6 and 8.1 are not good choices for a 5300.
And if we are talking about 7.6 compared to 8.x, there is no comparison. 7.6 is just too painfully out of date. Apple introduced partial memory protection and multitasking with Mac OS 8.0 (both were advances that came from the Copland project).
As someone who has had both a 2300c (running 8.1) and a 5300c (also running 8.1) sitting next to my Quadra 950 (running 8.1), I can tell you that in common tasks my Quadra felt faster even while running on a 68040. Why, because the 2300c (just like the 5300) was using a 603e at 100 MHz and trying to emulate major parts of the operating system (which the Quadra wasn't having to do).
I use my 2300c (currently running 8.6) as my primary school system (after I bumped the RAM up from 12 to 56 MB). It runs great and I would never even consider crippling it by running an OS on it that it would have to run large amounts of in emulation.
People may not remember this, but when Apple released Mac OS 8.5 they had a slogan...
"It is like getting a whole new computer for $99.00."
That was aimed at people with slower PowerPC systems who would see a performance bump by moving from systems like 7.5.x, 7.6, 8.0 and 8.1 to 8.5... people like us who own systems like the 2300c and the 5300 PowerBooks.
Again, unless you have restrictive amounts of memory (16 MB or less), there is no good reason to move backwards from 8.5 to 8.1 or 7.6... and a major reason why you should stay at 8.5 (and even consider moving up to 8.6).
