The chip speed is probably marked on the package under the white "gasket". However, it would be best not remove it as you don't want to damage the die with the heatsink. I believe that 333W is the module speed and if it's running ok at 333 well then there you go! :)
Check the floppy drive connection. Also check where the Novy board was attached to the 68000 processor to make sure there's nothing loose or broken there.
That's a nice Novy card, 50Mhz '030.
And yes, you have to bend the frame a bit to install or remove the board with the card attached, that's...

So, no, you can't use a lithium ion battery in a Macintosh Portable, at least not without extensive modification of...

But I have not seen everything. :)
And I had forgotten about the Portable, which iirc supports 9MB but it's kinda unique in many ways.
