Looking for kitchen cabinets

We are in desperate need of regrouting the tiles in our kitchen (new countertops would be better, but we're turning it into a rental and dont want to drop a ton of cash!). The problem is one or two of the tiles around the sink have become loose and I'm certain water has gotten underneath. Can we just pop the tile out and clean it up then use some liquid nails to glue it down before rerouting or do we need to do something else? This whole project will be a first for us, so we are trying to keep it simple, but also want it to last. Thoughts?

OK, maybe it will be more than a few weeks before I get to this part of the kitchen remodel at this rate, but I was looking last night at the new pantry I've framed in. Hmmm, how to equip it with the best shelving options? This will be a long/skinny room under 4' wide and maybe 7' long, shelving on three sides. Probably no more than 12" deep anywhere. I want to max out the space, and recognize that light stuff like boxed goods (cereal, etc.) more lightly loads a shelf than cans & bottles. I swung through the shelving aisle at Home Depot recently and eyeballed -- quickly -- the choices. Conventional wire shelves (oh, almost definitely avoiding solid shelving) in cut-to-length sections of the "closet type", yes they have regular and heavy-duty but the latter looks like the same diameter wire, just more densely spaced. Available in white or taupe, no chrome finish. Alas, unless someone tells me different, stuck w/plastic clips and brackets to mount to the walls, limiting the load-bearing capability. Alternatively, free-standing heavy-duty chrome shelving units. Alas, no ability to control unit length so unless very lucky, I'll have wasted space if I can even fit them in. Plus, few shelves per system if I want to space them closely, as one would for cans (yes, I can buy multiple units and throw the excess uprights away). Well, then -- what options am I missing? Not only types of products but sources (not every purchase has to go to H-D or Lowe's, you know). I'm thinking something built for storing something heavier than sweaters. Maybe a garage-oriented product?
