Welcome to the world of vinyl! As you may have already noticed, you have entered a world that rivals golf in terms of the number of gadgets/upgrades/sound enhancers out there. While most of them I think are silly, I think there are three worth investing in. First, as noted earlier, is a really good anti-static lint brush that you should ideally use every time you play a record. The other two are really only relevant if you are going to buy used records (which it sounds like you are). First is some sort of record cleaning device. These range from $500+ automatic record vacuums to a cheap set of lint-free cloths. While I hear great things about the vacuums, I lack both the space and funds for that kind of thing, so I use the SpinClean record washer (

The third item I would get is some kind of record weight/clamp which fits over the spindle and holds the record tight to the platter. Again, these range in price from $10-$200+, but it's not something I would over-spend on.
The last thing you may want to consider is some kind of platter upgrade or platter mat upgrade. Looks like your TT comes with a rubber mat, which is a nice upgrade over the typical felt. Down the road, you may want to look for an acrylic platter to replace the aluminum, but I wouldn't worry too much about that right now, just enjoy the music!
