05' F250 5.4L V8 gas Converter problems

I have a 05' F250 5.4L v8 gas Fx4 package w/ 97,000 MI.
When i bought it someone had put a K&N filter system on it that i keep clean regular My check engine light was on and I had to replace all my spark plugs and coil packs 3 of which were seized up. Now my Converters are bad.
Just wondering what people think of the K&N clean and oil filter VS. the one you can clean with soap and water and no oil? Also I am thinking of doing straight pipes and eliminating the converters but don't know what to do about the sensors and the computer. I am looking at getting a chip to program the computer but they are so expensive. I am at the point I cant really afford the converters because they have to be ordered from ford and the chip is not cheap. Oh ya my mileage has gone from about 14 or 15 to about 10 or 11 mpg now it is killin me and I have no power going up hill now.
I hope to get some good ideas anything helps. Thanks!!

Also does anyone think the K&N filter could have caused all these problems if so what would you reccomend instead? I was also lookin at the FU chip if anyone has heard of it off of power hungry perf.
