Hi Amel. I know it seems rather overwhelming when you're a first time mom, but you're off to a good start.
Let's see if I can help with a few of your questions.
Up until your baby is a year old, milk is the
primary source of her nutrition. During this time it is important to introduce solids for supplementary nutrition, but it helps to keep in mind that milk will be the most important part. Therefore it is recommended that you offer milk before solids so that she is still getting all the proper nutrition from her milk and not filling up on solids first. This is especially true for the first few months when starting out with solid foods. Often after 9mos or so, and depending on if your LO is breast or bottle fed, you might then decide to switch to offering solids first. Until then, keep offering milk first. Here is a link with some info about how much milk your LO needs. Make sure that she is getting the proper amounts of milk before filling her up on solids.

Her tummy is still so tiny, and again since milk is more important, you want to make sure she is getting all her milk. If you start to notice she seems to want more solids, and her milk intake is not dropping, then you can try offering a little bit more. But always make sure she's getting enough milk.
When it comes to EASY and solids, the easiest way to look at it is that milk feeds are the E, and solids are part of the A (usually offered 30mins-1hr after milk). Remember that solid food before 1yr is for fun and exploration, so try not to think of them so much as 'meals' just yet and more as part of activity time. Here are some sample routines:

Solids before a year will still offer a good part of your baby's nutrition, but as long as you are offering a good variety of solid foods, your baby will be getting everything she needs. As she gets older you will be able to incorporate lots of healthy foods into her repertoire
Some things to look out for with regards to reactions are rashes, either on the body or on the bum after a bowel movement, runny nose, diarreha and/or vomiting, gassiness and tummy upset, fussiness or disrupted sleep. It is tricky sometimes to know if a food is causing these issues or if it is something else. A really good idea is to keep a log of new foods introduced and any reactions that they may have caused. Sometimes you have to play detective.
