changing radiator hoses today, few questions

What I did was get some liquid degreaser and pour it over the lower radiator then after a while flush it off with a hose. Using air is ok but not a compressor with high pressure, I used a small vacuum and reversed the air to blow into the radiator to clear old stuff..It's gentler and won't harm the radiator. I'd also use some "Never Seeze" on the fan shaft and I wouldn't hit the wrench with a hammer, too harsh. Just a snug push.

first fill i was able to get just about a gallon of my supertech 50/50 in there(some in the expansion tank, and the rest in threw the bleeder hole in the T fitting). started up the truck and pored another half gallon in. put the cap back on the expansion tank and let it get up to about 195 then shut off the engine. let it cool a little and noticed the expansion tank was a little lower so topped that off, cracked the bleeder open and a little air came out. started up again and let it rise to like 204 before the thermostat finally decided to open and i could feel heat come threw the vents in the car and the temps went back down below 200. turned off the engine and let it cool again.
added more fluid to the expansion tank(just about 2 gallons into the system now) and with out side temps of 65 today, i did a run down the highway and temps were bouncing between 186 and 188. at the stop lights it did rise up to 203 for a moment then went back down to 199. got in the garage and let it idle for a good 10 mins and it sat steady at 197. my local walmart didn't have any water wetter, but will get some of that in there soon. will keep an eye on the expansion tank this week and add as needed.
thanks for all the help from you guys. id say the worst part of the job is the hose clamps can be a little difficult to get at at times. and that water pump hose with the plastic piece is a bit of a pain too. but the water pump looks easy to get to and the fan and shroud and all that comes off easily too. also the hoses that pull off all the metal fittings on the system i ended up cutting off with a knife blade but im sure if you wanted to save the hoses u can wedge around a flat blade screw driver and pull at the same time and wiggle them off.
