Lisa, a foam roller is a device that you can use for deep-tissue massage. For the IT band it looks like this:

When you get the spot that feels sore or lumpy, hold that until it feels less sore and lumpy. It should be a little uncomfortable, but not horrendously so. If it's too awful to contemplate, running a rolling pin over the outside of your leg is similar but less intense. It's best to use the roller when you are warmed up, for instance just out of the shower, and to do some gentle stretches afterwards.
As for the glute stretch, there are a couple of versions that are a little less intense.
To start with, pull the leg toward the shoulder of the same side. From there, you can move it toward or away from the midline to get the stretch where you want it. This gives you a glute stretch in the top leg and (maybe) a psoas stretch in the bottom leg. If you don't want the psoas stretch, just bend the bottom leg and place the foot flat on the floor or bed or wherever you are.
Also, this is a piriformis stretch, but it can be a glute stretch as well if you have the ROM to cross your legs above the knees:
As with the other stretch, you move your legs around until you get the stretch where you want it.
In both of these, you are stretching the top leg, BTW.
The woman on the picture is obviously NOT a hippie!
Really? Of course, it's likely that she is not a THR patient, because very few people her age are, but why "obviously"? I do that stretch with slightly more ROM than she demonstrates. Actually, I do this version of that stretch:
So, don't underestimate where you may end up. We all know about
Shugaplum, right?
