The amp question should be considered in tandem with your speaker choice. I would keep to the higher impedance with a relatively flat impedance plot and higher sensitivity end of the spectrum, such as a minimum of 89dB sensitivity and preferably 8 ohm impedance. That will mate well with tube amps and particularly single ended triode amps if you choose to go that route.
A good conditioner can make a big difference, particularly in high resolution systems. If you are keeping the budget low, it may not be a priority, at least at first. You can always add one later. My advice is always to stretch the budget on what you absolutely need, one piece at a time, then upgrade things like cables etc. later.
