Here is a good lift:

I have one that looks exactly like that but it has the "Sears" brand on it. I paid around $100 for mine at the local Sears. It came with a set of straps so you can secure the bike to the stand. Depending on which bike I am working on, I might occasionally put some boards between the stand and bottom of bike to change the contact points or just to give it better stability. I use it for everything from the kid's little 50s up to my BMW R1200 GS. I think Harbor Freight sells one just like it.
Chains are either connected with a rivet master link or a clip master link. The rivet master link will look like all the other links in the chain. However, if you look at the end of the pins that connect the links, the ones on the master link will have a hole in the end of them and the ends will be flared out. That is done with a rivet pin that is pushed into the holes. This keeps the link plate in place. A clip style link will have the pins like any other link, but the ends of the pins don't have holes. Instead, they have a small groove around the circumference just before the end of the pin. The plate goes over the pins and gets pushed down below those grooves. The clip then sits on top of the plate and clips into the grooves on the pins. Technically, the rivet style is more secure. However, the clip style is easier to install and especially to remove.
To remove a rivet style chain, just cut a link with a dremel tool (if you have one) and remove the chain. Before you install the new chain, you may have to remove a few links to get it to the right length for your bike. This means you have to remove the head of one of the link pins so you can push it through and disconnect the unwanted links. I usually use a dremel for this, but you have to be careful about damaging the plate that remains on the part of the chain you will be using. Once the head is cut off, I use a pin press from Motion Pro to push it through. If you have a bench vice, you might be able to rig something else to do the same thing.
Once the chain is the right length, and you must also account for the master link you are about to install, you thread it onto the sprockets and either rivet the master link or clip it. Either way, you have to get the master link in place and get the outside link plate pushed down over the pins. This is where a press comes in real handy. The Motion Pro kit I have has a press plate that completely covers each side of the master link so you get an even push on both pins and the outside cover plate. Then, once the cover plate is on, the kit has a riveting pin for spreading the ends of the rivet style link. Otherwise, you just slip on the clip with the open end facing opposite the direction of chain travel.

Bead breaking on the tire can be done with a big C clamp if you have one. Or, you can sometimes put a piece of 2 x 4 under the edge of the tire (but NOT the rim) then stepping on the upper side of the tire right above the 2 x 4. Lastly, if you like tools...

I highly recommend watching some tire changing videos on YouTube. There are tons of them. Watch 3-4 and among them you will pick up most of the tricks. You definitely want something to "lube" the tire so it will slide on/off the rim easier.
Don't forget you need to balance the new tires...

This or something similar work real well. You will need weight as well.

Again, watch a few YouTube vids on how to balance and you will do fine.
