Word order is VSO (Verb Subject Object).
I'll try to give a very basic overview of the present tense.
PRESENT TENSE - VERBS WITH ONE SYLLABLE, eg. glan (to clean), cuir (to put)

Glanaim - I clean
Glanann tú/sé/sí - You/He/She clean(s)
Glanaimid/Glanann muid - We clean
Glanann sibh/siad - You/They clean

Cuireann tú/sé/sí - You/He/She put(s)
Cuirimid/Cuireann muid - We put
Cuireann sibh/siad - You/They put
Ní chuirim - I do not put
An gcuireann tú? - Do you put?
PRESENT TENSE - VERBS WITH TWO SYLLABLES, eg. críochnaigh (to finish), éirigh (to get up)
A, O, U = -aím, -aíonn, -aímid I, E = -ím, -íonn, -ímid
Críochnaím - I finish

GENERAL NOTES
Ní + séimhiú (h).
Ní adds the letter h to all verbs except those starting with vowels or the letters st, l, n, r, sm, sp, sc. These can be remembered with this mnemonic: ST eLeaNoR SMiles in SPanish SChool.
An + urú (Mb, Gc, Nd, Dt, Ng, Bp, BHf)
An eclipses the letters b, c, d, t, g, p, and f. All that means is that you put another letter in front of it. You can remember which letters take which eclipses with this mnemonic:
My Brother
Got Caught
Not Doing
Dishes Tonight.
Nobody Gets
Blueberry Pie
Before He Finishes.
I hope this helps to clear a few things up. I completely understand your frustration. Irish can be an incredibly difficult language to learn from scratch. Nevertheless, I hope that you continue to learn it because it is a beautiful language that really needs more speakers!
