Looks like you are set up to go - but get the manual first and read the first part about the reloading process and understand that. I don't know if Lee has changed their scale but the original scale was very limited and extremely sensitive - more than was necessary. RCBS 505 or similar - if available - is probably a better choice.
I loaded for years with everything in a salesman's case except components. I kept a couple C clamps, a small piece of pine, and grabbed a towel when I needed to reload. Towel on the dining room table, press on that, board under the table, and clamp the whole sandwich together and had a very stable loading platform. Load what was needed and pack the whole thing up and nobody could see that I had done it. I would add a pistol powder measure to your shopping list. Measuring every charge isn't necessary - especially for a revolver. Having a scale to set your measure is essential. I used a scale simply to confirm that my powder measure - dip, pistol powder measure, or RCBS measure - was accurate. I wanted to confirm and a reliable scale is the only way to do that.
Lee dies come with a shell holder, the only ones that do. Every other brand requires you to buy a shell holder separately. For years I cleaned primer pockets with an appropriately sized screw driver.
Think about why you want a portable setup. A press is the basis of the reloading set and is used to load and nothing more. To take it out to the range or camping is a romantic idea, but it's much easier to load your ammo at home and only bring the ammo! A solid press mounted to a bench or table is much easier and faster to use.
