i'd personally pull the front off (assuming it's like
ibiza/mk4 golf)
i usually do it in this order;
disconnect all wiring and plugs first + battery out. (pull loom back and out of the way)
then all pipes and hoses ( if you are unsure about where they go back leave one end attatched) and related items rad /header tank/ic etc
then driveshafts off
gear linkage disconnected (from gearbox end)
then down pipe off/ pulled back
like i say i'd take the whole front panel off, gives you more room and less likely to damage anything when removing/refitting
assuming the car is on axle stands and you've pulled the front off put something under the engine to support/take it's weight then undo the engine/ gearbox mounts (dogbone first)
i have a dolly/wheely board that i put under the lump and once its all disconnected just wheel it out with the gearbox still attatched put it next to the replacement item and swap all neccesary parts across. try and do as much as poss while it's out. then put the new lump on the wheely board/ dolly and roll it back into place and reverse the process as you removed it.
have a pot/ bucket for all the little clips bolts you remove too and just be methodical.
also don't forget the a/c will need depressurising ( don't breath the gas in) and recharging afterwards.
it's usually sensible to fit a new clutch while you got it out and is easily accessible.
when it's back in, new coolant oil and filter.
how to suck eggs probably i know.
maybe some bits i've missed but should cover the most of it.
