I saw a Olevia LCD screen that i thought i wanted at Comp USA and i saw a bunch of trailing and ghost images on the fast moving images. Would a better refresh rate cure this? If so whats a good rate? I think this TV was 12MS or 8ms?

You are on the right track, but you have to be careful about marketing traps. Also, the correct term is "response time". Don't get it confused with refresh rate. Refresh rate is how fast the entire screen refreshes, where response time is how fast the individual pixels update.
Anything with 10ms or higher, you are going to see ghosting in a football game. Anything under 8ms, you are probably going to see minimal or no ghosting. Now, you see TV's advertise 4ms.
If you look at the real technical specs of a LCD TV, you will find there are more specs than just one response time. Companies tend to use an average or pseudo average amount to obviously favor uneducated to buy their TV's. There is an average low, average high and overall overage. A median value would probably be a more true value.
12ms can mean that low is 7ms and high is 17ms. If you had a TV that had a 11ms and 13ms, this would perform better than the previous TV, even though both TV's would have an average 12ms. I have worked in marketing for projectors, so I know how they fudge numbers. It is legal deception, though it is unethical.
That is why people like plasma and DLP TV's because they respond alot faster than LCD's.

This was a know issue with LCDs (actually the other main technologies such as DLP and Plasma are not completely immune either) however it has improved a lot of the last few years. Refresh rate for LCD TVs is usually 8 ms with some computer screens being around 4 ms. You may want to consider one of the other technologies in your television search and compare some of the new DLP and Plasma TVs also. I have found that DLP seems to provide a good option for most people based on quality and cost. Along with the fact that the bulb can be replaced so you do not have a finite life for your TV.

It looks more realistic than world. It's really strange at first. You might not like it, so check it out at the shop.
