Live Game Situation - How do I adjust?

[Nate_Dogg]

Playing 2-5 NL (uncapped buy-in) at the Horseshoe in Tunica. Most players in this game are deep stacked. I have $1200 and about half the table has me covered. Here is the problem - A loud-mouthed, but somewhat talented semi-LAG is sitting to my immediate right - which most would say is a good place to have him except that he is "Live-straddling" about every other hand when he (and me by definition) are in late position. So basically every time I'm in late position I'm effectively under-the-gun. After asking for a seat change how do you adjust your starting hand selection and PF raising standards. This was the "main game" table and I would classify the talent level as above average, but still beatable for a live game. I would also say it is more aggressive than average.
