Hello again, fms!
Unfortunately I don't know any resources, but I can give you some examples.

Indeed, it sometimes acts kind of like present continuous. Together with "
-ma" (illative) and "
-mast" (elative) they form
relative future -
relative present -
relative past triplet. For example:
hakkan olema ~ I will be / exist
olen olemas ~ I am, I exist / am existing
lakkan olemast ~ I (will) cease to exist
But more often than not they also bear locative meaning. For example:
lähen sööma ~ I go / am going / will go to a place where I (will) eat
olen söömas ~ I am at a place where I eat / am eating
tulen söömast ~ I come / am coming / will come from a place where I ate
"
-mas" can also mean that something is about to happen:
Olen kohe koju jõudmas. ~ I am about to get/reach home.
"
-mast" is used to indicate prevented actions:
takistan minemast (I obstruct from going),
hoidun minemast (I refrain from going),
keeldun minemast (I refuse to go),
keelan minemast (I forbid to go),
hoian minemast (I keep from going), etc...
"
-mast" is also used with "
tere", "
suur tänu" and the verb "
tänama":
Tere tulemast!,
Suur tänu tulemast!,
Tänan tulemast!, etc...
Then there's also "
-tama" which is passive "
-ma" (not to be confused with verbs that naturally end with -
tama). I think it's only used with the verb "
pidama" as '
must', '
have to', because in that case "
pidama" doesn't have passive voice. For Example:
See pidi juba ammu valmis ehitatama. ~ this had to be built a long time ago already
"
-maks" is exactly as Virankannos said, '
in order to do' (sometimes simply '
to do'). It is equivalent to "
et" + infinitive:
Pidin vara ärkama, et õigel ajal tööle jõuda. ->
Et õigel ajal tööle jõuda, pidin vara ärkama. ->
Jõudmaks õigel ajal tööle, pidin vara ärkama ~ in order to get to work in time, I had to wake up early
"
-mata" acts exactly the same way as abessive case for nouns.
