Can I use an 8 speed sti shifter with the 7 speed rear cog? is the spacing the same and I will have an additional click on the shifters or will there be problems with derailuer alignment?

Even though the spacing is technically different (4.8mm for 8s vs 5.0mm for 7s), it is close enough that it works fine. Set the RD limits first and use the low (largest rear cog) limit to lock out the 8th click. Then adjust the indexing from the middle rear cog.
