Maybe try replacing outliers with the median value in the neighborhood.

To remove the nan-s use one of the inpaint-tools found on the matlab file exchange. Search for both inpaint_nans and inpaint.
To remove spikes use medfilt2, or if you do not have access to that function, use medfilt1 in both directions.
