Gearbox / Clutch work in a Paseo (5E-FE) - a few questions

[batterypowered]

Hi all.
I'm undertaking my first big mecanical job on my Paseo at the moment, and that is changing the clutch. I'm totally new to doing in depth car mechanics such as this, so apologies if my questions seem obvious - I'm just doubting and/or double taking myself in this process

• Gear linkage cables: they are disconnected from the gearbox, but I have no idea how to physically get them out of these clips on the gearbox. Are they just meant to slide out?

• Speedometer cable: I'm guessing this is just meant to unscrew? At least that's what I've seen from other people online.

Once these are off all I've really got left is to drain the fluid and drop the gearbox. Anything to look out for during this process?
Thanks
