I think I'd pass on a cockpit FP gauge, unless you just have a hole to fill, enven then make it electrical. When using a RRFPR, I felt it was good to have for tuning. I have a small mechanical screwed into my Paxton adjustable. When I want to check things out while driving, I replace it with an sending unit, which I wire up to the existing VDO oil pressure gauge. With programable fuel management, I'd just set it at 3 bar and pretty much forget about it, unless you are working through a problem.
I doubt that you will find the EGT gauge very useful, although it's still nice to have. I've got one that came with my engine, it's a two gauge in one, the manifold was drilled by the 1-2 port and again at the 3-4. I found it useless, for on the street tuning. I plugged the holes and removed it, there is enough stuff there already to be monitoring. I may put it back in later, pre and post turbine.
I have also found the A/F gauge basically usless for tuning at 5K and above. I've tried new 3 and 4 wire sensors, even tried different grounds for the gauge and 4 wire. The gauge will show lean, when you are really rich, you can richen to the point of misfire and it's lean on the gauge. You can lean it, till the gauge becomes active again, but by this time, you are really leaner than you want to be. Although I am satisfied with my values in the upper RPM ranges, I'd really like to know what the A/F ratio is and have ordered the stuff to make a DIY wide band, thepartsbin.com has the NGK 5 wire sensor for about $125. I've talked to several people that have gone this route with sucess and sensor life is good with unleaded fuel. I highly recommend that you put one together also, sense, you, like I live nowhere near a dyno, unless you can borrow one as KevinK suggests.
There are several systems that offer auto tune, type features. What isn't realized, is that to use the feature, there must be a wideband O2 sensor which adds a lot of dollars to the cost.
I didn't build the engine, but top end was built with new stock parts, probably not including cams, which are 86T. I've had it up to 8K where it still seemed happy. Although rev limited to 7.5K, it seldom sees above 7K as the transmission isn't happy about shifting above that.
