3rd Gen Prelude filter/oil types?

Hey! Sorry if this is the wrong forum (or just a really dumb question).

The story is that I just got my car back after an automatic transmission rebuild, I assumed that the car would get serviced after one of these but I guess I was wrong.

I'm pretty capable of changing oil and filters (I am sure there is a DIY here anyway).

I'm just wondering what engine oil, oil filter, air filter and spark plugs other people use on there 3rd gen, mine is just a stock engine with about 80 000kms on it.

I also need to change a pipe that goes from the top of the radiator, I have no idea where to but if anyone knows what pipe I'm talking about let me know!

If anyone can help it would be greatly appreciated, if you havnt noticed I'm pretty new to this! Thanks:)
