We will be arriving at Arlanda around 3:30 pm on a Wed. in mid August so I'm guessing it will be near 5pm when we arrive at Central Station in Stockholm. We need to get to the Mornington Hotel, which I know is only 1 metro stop away, but we will each have 1 carry-on size bag. Should we opt for a taxi instead of braving the T-bana? How much would the taxi cost & where is the taxi stand? If you add the taxi to 2 Arlanda express tickets would it be about the same cost to just get a taxi from the airport?

My hotel was 3 metro stops from Arlanda Express. From the airport, I took the Arlanda Express and then a taxi---by that time I did not save any money. My hotel told me about Airport Taxi, I should have take them instead. I did take an Airport Taxi from the hotel to the Airport and it was essentially the same cost, just for me. So it would likely be less expensive for the two of you, and certainly much easier. The Airport Taxi cost me 390 SEK. It is my impression that the hotels will recommend, if you have to take the express and then get on T-bana, you might as well take an Airport Taxi (they just do airport runs).
If you can manage your bag, the t-bana won't be an issue. Rush hour in Stockholm is not like rush hour in London. There is a special 2 tickets for 300 on the Arlanda Express in August. After you arrive at the Central Station, you then transit down a long corridor to T-Centralen and take the tunnelbana to Östermalmstorget ( direction Mörby Centrum on the "red" line). A single ticket on the t-bana is at most 44 SEK, so for two people in summer you will pay a max of 388 SEK.
Taxis in Stockholm are not regulated, so it is important that you choose a reliable company. Taxi Stockholm, Taxi Kurir, and Taxi 020 will all charge a fair price. for example, Taxi Stockholm offers a fixed price from the airport for about 520 SEK; the other two companies also offer a fixed price. When you go to the taxi queue outside Arlanda, make sure to choose one of these companies and confirm the price before getting in. If you were to take a taxi from the Central Station, there is a queue close to the tracks (follow the signs).
I'm not familiar with the company that Wray suggested. If you book with them, check the price from the airport which is generally different than going to the airport.
If you purchase the Stockholm Card it includes the commuter train from Arlanda Airport to the Central Station, but requires an 85SEK per person supplement. There are two trains an hour at about 40 minutes ride time. Worked well for us from and to the airport.
Edit: Don't forget that ..."an unlimited number of free trips on subways, buses, commuter trains, trams and boats with SL Sjövägen are included in the Stockholm Card" so you can continue beyond the Central Station on public transit to your destination.
