US 550 is a mighty fine highway, no issues. There are not a lot of services between Bloomfield to Albuquerque so make sure you have plenty of fuel. There are places to get fuel, of course, but I prefer fresh fuel from high volume sellers.
Just me, personally, but I'd take I-40 from Albuquerque towards Amarillo, jump off onto US 287u (very good road) towards Dallas-Fort Worth. I'd cut just south of DFW to miss that mess. From there you could work your way down to I-10, or just pickup I-20 eastbound to Shreveport LA and head to FL.
Best wishes to you, have a safe and enjoyable trip.
