The dish would have to be re-aimed because Direct and Dish use different satellites. Have it installed by a Dish installer, they'll install the most up to date equipment and it won't cost you anything. That dish you have is outdated and only used for basic installs anymore.
An install done by E* will either be free with a 24-month commitment or probably $99 without a commitment. You can do it yourself of course. If you don't want any HD programming, then a Dish 500 with a Twin LNB will provide for 110W and 119W. Your standard definition locals should also be on one of those if you need them, but without knowing exactly where you are, I cannot guarantee that.
If you are thinking about HD at some point in time in the near future, you might consider going ahead and setting yourself up now and not waste money on purchasing SD receivers. I would imagine you are in an eastern arc market being in NC and would need a Dish 1000.4 antenna. If you let us know your zip code, we can tell you for sure. The entry level mpeg4 receivers for the eastern arc are not much more expensive, if at all, than the SD receivers you are considering. If you are in an eastern arc area, this is the setup E* will provide you even for SD programming, if you are a new customer. Later if you go for HD programming, everything is already in place. You will incur monthly costs for the receivers. I would contact a local retailer,
www.Dishstore.net, or E* to see what everything would cost. If the upfront cost for receivers seems too high, check the prices on eBay, but remember you will pay a monthy charge for any receiver except the first whether you own it or lease it from E*. If you go through E* or one of the retailers and not do it yourself, you will get at least one receiver free and maybe all of them with a 24-month commitment. You just need to check.
If you do a web search you should find detailed instructions for installing a Dish 500 system along with the pointing angles. You can use the install instructions for a 500+ but use the pointing anles for a Dish 500, not the 500+ and ignore the 118.7 LNB info. Depending on the receivers you install you may also need a switch.
