For the dependencies and pre-requisites, just read the Notes recommended by the RTCCTOOL run. when you downloads the ST-PI or ST-A//PI or even any patch, it's information file is always there with it in marketplace which tell what pre-requisites should met before that particular patch can be applied successful. For 'pre-requisites', here means, the support pack/patch level which should already be there before applying the current one in question.
And, like if we do not have any SP of ST-PI or ST-A/PI already in our SAP system, then to install them for the 'first time', we need to download the 'installation files'. If you already have some patch level of ST-API or ST-PI in the system, then we need to downlaod the 'delta upgrade' files for each of them. Read those notes, everything mentioned.
For normal precaution, just make sure that /usr/sap/trans filesystem has enough space and do this patch activity in less user load time, however st-pi and st-api woudn't be affected much even with user loads.
