Missions & Complexes

I was wondering if anyone had any information into how exactly certain standings work, for example:

There are 3 standings, faction, corp and personal, I get how faction and corp work for the most part however a couple of questions for you mission pro's re personal and corp standings...

Does a personal standing affect the quality of mission you get ie.. a higher standing will reap much higher LP and bounty payouts?

and does having a corp standing of +10 have any benefit over +7 say or do they bassicaly mean the same thing.

Mission LP's have a base amount that can be increased by training:
1) Security Connections
2) Distribution Connections
3) Mining Connections


Mission rewards have a base amount that can be increased by:
1) Agent standing
2) Agent location (system security level)
3) Level of Social skills trained


Above +6.50 (modified) standing, NPC Corporations will stop taxing Refinery use.
Above +7.00 (modified) standing, NPC Corporations will allow access to all of it's Agents.
Above +8.00 (modified) standing, NPC Corporations will allow Jump Clones to be installed.
