Three Peaks Alfy is giving good advice! As for the wire kicking back on you you may very well have a bad ground conection to the work peice check your ground wire ends to make sure that they are not dammaged or such. also you cand set your feed roller tention by angling the nozel at 45 degrees into the palm of your gloved hand and pull the trigger the wire should coil up tighten the drive rollers until the wire does not feed into your hand then back off the tention 1 turn.
.035 / 0.9mm solid wire will work perfectly for your aplication no need to go any thicker unless you plan to weld steel that is 2 inches or more thick. use the 75/25 argon/carbon. Flux core wire is OK but if you have a bottle and regulator get rid of the fluxcore!! or you could use up the flux core with the gas (however it will burn alot hotter than normal this way.). The angle grinding your welds is not a good idea you need your weld to be strong as a posible.
I would recomend going to a lighter lens in your hood if you are having a hard time seeing you work peice.
The key to welding is getting comfortable. with steel you can either push or pull= (Like special k's diagram) Aluminum is different you should always push to prevent build up (night crawlers)
good luck
Also you can adjust your wire speed while welding on a peice of scrap you simply adjust the dials till it performs well for you I can usually get a mig to near no spatter just sounds like bolt of electricity.
