Your batteries if group 27 are about 85 AH each so the bank is about 170 AH total.
If your main use for the inverter is the laptop a small 300 watt inverter is all that is necessary, if that large. Or better yet but a 12 volt adaptor for your laptop which is more efficient than any inverter.
Your battery bank will not properly support an 1800 watt inverter like the Xantrex HF1800 anyway. It will pull 180 amps at max output and that would only last about 15 minutes on your bank. Even if your battery bank was large enough for this the larger the inverter the more power they consume if on without a load.
As far as an AC panel, I agree with the previous poster that the Blue Seas panels like your DC ones are excellent quality. I'm not sure how many circuits you need nor how much space you have. The Blue Seas 8027 shown below is the same size as one of your DC panels and would probably have enough circuits for now with a spare or 2.
