While aluminum radiators can work, I would avoid the three-core version. The added thickness can cause clearance issues , but just as importantly, aluminum tubes are much wider than the brass ones. Air often has a hard time getting through all the extra fins and tubes when your car is sitting still. Additionally, by the time air has gone over the first two tubes, the air is already very hot and unable to cool the third one, when air flow is slow.
Your best bet is a good 3 core brass, or 2 core aluminum radiator.
High flow waterpumps can be all right, but if you rev to high RPMs, some of them have problems with cavitation, leading to impeller and housing failure. Stock ones work pretty well.
Electric fans are fantastic for cooling your car at a stop, and they steal less horsepower than belt-driven fans too. However, to run one, you may have to upgrade your alternator, and install proper relays.
