Absolutely echo buying the best kit in all areas that you can. I also still have my first Manfrotto tripod i bought when starting out, over 10 years ago, I have only just replaced it for a carbon fibre Gitzo.
Memory cards, multiple smaller rather that one or two really big ones. A 128gb card is a lot of images to loose if the card becomes corrupt.
Thinks such as lens clothes, rocket blower, nice comfortable knock strap such as a padded optech one or peak design/blackrapid should strap allows you to hand the camera from your neck/shoulder and frees up both hands if you need.
I wouldn't bother with uv filters as above, waster of time. The quality of glass in your lenses will be superior to that in a uv filter. Just make sure you pop on the lens hood and that along with being careful will be enough.
To start with if I am honest, if budget is limited, get the newest version of the 18-55 or 18-135 lens and just learn your camera, learn about photography, enjoy taking pictures and start to find and get an idea of what you enjoy taking pictures of. Then you can begin to think, well, if I like landscapes I want a good quality wide-angle, or if you like wildlife you want a good quality zoom lens like a 70-300 or better. But if you are just starting out don't go crazy straight away.
As a general rule lenses will always outlast bodies, so always invest in good glass, bodies will come and go but glass lasts a lot longer.
No real harm in having a prime lens early on, it will let you play with shallow DOF and also teach you about taking things steady and composing carefully, if you need more or less in the frame you get to use gods zoom to do so (your feet, walking forwards or backwards) and a 50mm is cheap enough, STM is most recent and can be had for about £95 quid or so.
Main thing is to get the best bits you can right now, enjoy it and get out there and take pictures and learn!
