Is Toric IOL risky? Will it significantly improve 1.5 astigmatism?

[LifesABeachum]

I'm a healthy 48 yr female with surgery on May 6, 2010. My approx RX is Right= -13.75, +1.50, 95 and Left= -10.25, +1.0, 80 and a 1.50 reading in both eyes.  My right retina detached in 1987 and cryo surgery done in left. I have small cataracts in both eyes and my night vision has deterioriated significantly with headlights becoming "stars" - but no halo effect.  My day distance vision while driving is not very good either, and I'm tired of "coke bottle" glasses.  I wore hard glass contacts from 15 to 25 years old , but eventually dry eye, strong power with astigmatism made even soft contacts impossible.  I also have a pretty severe "floater" problem - after the retina surgery.
My eye clinic has state of the art techonolgy, and I have confidence in my doc.  He's recommended toric IOL implant- I guess the "limbus" incisions won't work for me.  My understanding is that after the toric IOL implant, I will only need reading glasses but that the need for reading glasses will be more noticable after surgery than before.  
My questions are:
1. Is toric IOL more reliable now than when first introduced in 2007ish?  Will this really improve my vision so dramatically that all I'll need is reading glasses?  
2. Will rubbing my eyes after surgery too much cause the IOL to dislodge?  Will rubbing my eyes too soon cause permanent "scratching"?  I have terrible habit of rubbing my eyes frequently - because they are so dry.
3. How common is dry eye issues from not lubricating the eye enough during surgery and how lasting are the affects?
4. Will the cataract surgery increase my floater problem more than it already is?  
5. Is it possible to "mess up" the IOL measurements?  I think I kept my right eye closed too long during the measurement process - is it crazy to ask for the measurements to be taken again?    
I sure appreciate your time in answering my questions - I will be asking them of my doc too - I just want to hear what a neutral source says too.

Dear Lifesabeachum,

The toric lenses have improved since their first introduction.  It is possible that your vision will improve so that you may only need reading glasses.  We advise against rubbing of your eyes after cataract surgery.  Dry eyes can worsen from the procedure.  Cataract surgery may cause a change in the floaters.  If there is any question about the accuracy of the IOL measurements, ask your eyeMD to repeat them.  I definitely recommend that you discuss these items with your eyeMD.

I have talked with my doc's tech and feel very confident to proceed. I didn't realize that rubbing your eyes too much after surgery will not risk dislodging the IOL, but rather risks damage to the eye incision and may rupture it.  She said I can wear the night guard during the day if I feel I need to.  She also assured the measurements were fine and that many are taken.  The machine indicates if it's not able to read a measurement properly.
