I’d make sure you put in a strong app for UIUC in their EA round. Hopefully you will get accepted into one of its honors programs. OOS public schools are likely to be as expensive as many privates, with less prospects for aid, FA or merit. Also you will not likely have small classes unless you get into an honors program.
You also need to decide if you want a small school/LAC experience or a large university experience. I think your list is generally reasonable. Hopefully for this next year UIUC will release early action decisions prior to year end, in which case you can shoot for more reaches if you get in.
