You should add a diode across the 10K resistor, Anode to power and Cathode to Reset, will keep the chip from attempting to go into High Voltage programming mode
I've not found the cap to ground to be needed. Likely the DTR cap makes it stable enough.
Also put a 100nF cap from Aref to Gnd, will be needed for stability if one is doing any analog measurements.
Actually, I got the diode backwards - should be anode to Reset, Cathode to Power. I'll fix my earlier post.
Want any spikes on the Reset line dissipated to the power line.Diode like 1N4148 will do.
The 10uF Electrolytic (usually aluminum electrolytic) helps with any big current ripples, while the 100nF help with higher frequency stuff and short term current demands.
You don't have any extras to remove. The last diode & cap get you up to the minimum for an Arduino.
