This is good, solid work. You should be lifting slightly more for the deadlift than you do for the squat; that you aren't suggests that you aren't going low enough on the squat. A good idea would be to film your technique then post it on /r/AdvancedFitness or /r/weightroom or similar, and ask for critique. But 100lb for deadlift is brilliant for just starting out.
I would also recommend recording how many sets, repetitions and your rest period. These dramatically change your workout and you'll want to look back to see how many sets/reps you were doing when you hit 100lbs.
If you have a smartphone then I recommend the Jefit app which will time your rest period. Even if you don't have a smartphone, I recommend recording your workouts using Jefit or even just a simple spreadsheet. Many people use just a simple journal they take to the gym which tells them their last workout results so they can attempt to beat them.
You'll then be able to use that wealth of data to see your improvements and design your next workout phase.
