You have three diagnostic ports (old fiat 3 pin connectors),ABS- at the ABS pump under the hood, Airbag- at the center tunnel underneath the rear seat, Engine- at the center tunnel on the passenger footwell behind the cover.
ABS and Airbag (unless you do not have the old Becker airbag unit) you can do with FiatEcuScan but engine (Motronic ML4.1) is not supported by FES so you need Examiner or a Bosch diagnostic tool, I have heard that UniDiag supports ML4.1 but I have never used that software so I can not tell.
Spark plugs - I have had good experience with Bosch WR56 and the four ground electrodes gaped to 0.65mm from the center electrode, stay away from iridium spark plugs (random misfire at "high" boost/RPM).
Filters - any decent brand of filter will do (I use a K&N panel air filter in OE filter box).
Oil - I have used a decent synthetic 5W-50 oil (not a exclusive brand) for years without problems.
